본 연구는, Semin과 Fiedler(1988)가 제안한 LCM(언어 범주화 모델)을 기반으로 지역 고정관념이 언어로써 어떻게 재현될 수 있는지 검토하였다. 보다 구체적으로, LCM에서 주장한 추상화 정도에 따른 4개 언어범주(행위동사, 해석동사, 상태동사, 형용사)가 한국어 단어로 구분되는지 검토하였다. 판별분석 결과, 한국어 단어는 5개 평가차원에 따라 추상화 정도가 다른 4개 언어범주로 구분되었다(연구1). 연구 1의 결과를 바탕으로 대상의 고향과 행위를 취업 면접 상황의 스크립트로 제시하여 지역 고정관념에 적용한 결과, 참여자들은 대상의 행위(인정 많은 대 지적인)가 대상의 고향에 대한 지역 고정관념과 불일치 할 때보다 일치 할 때, 더 언어적으로 추상화하여 묘사했다(연구2). 또한 연구3에서는 연구 2의 스크립트를 대상의 고향 대신 말씨로 조작하고 취업 면접 상황의 시청각 자료로(비디오테이프) 제시한 결과, 연구2에서와 동일한 형태의 언어적 추상화가 다시 한 번 나타났다. 한편 참여자들은 대상의 행위가 대상의 지역 고정관념과 불일치 할 때보다 일치할 때 더 내부귀인 하였고 보다 채용하겠다고 답했다. 이를 바탕으로 지역 고정관념에 따라 대상의 행동을 해석하고(즉, 귀인) 또한 실제 행동의도(채용의도)를 결정하는 데 있어 언어적 과정이(즉, 언어적 추상화) 매개하는지 알아보기 위해 매개분석을 실시했다. 그 결과 매개모형은 유의미하지 않았다. 매개모형을 제외한 연구결과는 가설을 일부 지지했다. 각 연구 결과와 그에 따른 함의가 논의되었다.목 차

Realizing the relaxion from multiple axions and its UV completion with high scale supersymmetry
Get PDFAbstract: We discuss a scheme to implement the relaxion solution to the hierarchy problem with multiple axions, and present a UV-completed model realizing the scheme. All of the N axions in our model are periodic with a similar decay constant f well below the Planck scale. In the limit N ≫ 1, the relaxion ϕ corresponds to an exponentially long multi-helical flat direction which is shaped by a series of mass mixing between nearby axions in the compact field space of N axions. With the length of flat direction given by Δϕ = 2πfeff ∼ eξNf for ξ=O(1), both the scalar potential driving the evolution of φ during the inflationary epoch and the ϕ-dependent Higgs boson mass vary with an exponentially large periodicity of O(f)eff, while the back reaction potential stabilizing the relaxion has a periodicity of Of O(f). A natural UV completion of our scheme can be found in high scale or (mini) split supersymmetry (SUSY) scenario with the axion scales generated by SUSY breaking as f∼mSUSYM∗, where the soft SUSY breaking scalar mass mSUSY can be well above the weak scale, and the fundamental scale M* can be identified as the Planck scale or the GUT scale. © 2016, The Author(s)675911Nsciescopu
Electroweak baryogenesis by axionlike dark matter

Funded by SCOAP3.We show that an axionlike particle (ALP) naturally implements spontaneous electroweak baryogenesis through a cosmic evolution strongly tied to the electroweak phase transition (EWPT) if it feebly couples to the Higgs field while giving a small contribution to the Higgs boson mass. The observed baryon asymmetry can be generated successfully if the ALP couples strongly enough to the electroweak anomaly. Also interesting is that the ALP contributes to dark matter, and its coupling to a hidden gauge sector makes the relic abundance insensitive to the cosmic history before the EWPT. The ALP explains both the baryon asymmetry and dark matter in a wide range of the couplings owing to the friction induced by the hidden gauge sector. To be compatible with cosmological and astrophysical observations, the ALP should have a mass in the range between about 0.01 and 30 eV, and is further required to be photophobic if its coupling to the electroweak anomaly is strong, constraining the field content and charge assignment of the UV completion.11Nsciescopu
Peccei-Quinn invariant singlet extended SUSY with anomalous U(1) gauge symmetry
Get PDFAbstract: Recent discovery of the SM-like Higgs boson with mh ≃ 125 GeV motivates an extension of the minimal supersymmetric standard model (MSSM), which involves a singlet Higgs superfield with a sizable Yukawa coupling to the doublet Higgs superfields. We examine such singlet-extended SUSY models with a Peccei-Quinn (PQ) symmetry that originates from an anomalous U(1)A gauge symmetry. We focus on the specific scheme that the PQ symmetry is spontaneously broken at an intermediate scale vPQ ∼ mSUSYMPl by an interplay between Planck scale suppressed operators and tachyonic soft scalar mass mSUSY (Formula Presented.) induced dominantly by the U(1)AD-term DA. This scheme also results in spontaneous SUSY breaking in the PQ sector, generating the gaugino masses (Formula Presented.) when it is transmitted to the MSSM sector by the conventional gauge mediation mechanism. As a result, the MSSM soft parameters in this scheme are induced mostly by the U(1)AD-term and the gauge mediated SUSY breaking from the PQ sector, so that the sparticle masses can be near the present experimental bounds without causing the SUSY flavor problem. The scheme is severely constrained by the condition that a phenomenologically viable form of the low energy operators of the singlet and doublet Higgs superfields is generated by the PQ breaking sector in a way similar to the Kim-Nilles solution of the μ problem, and the resulting Higgs mass parameters allow the electroweak symmetry breaking with small tan β. We find two minimal models with two singlet Higgs superfields, satisfying this condition with a relatively simple form of the PQ breaking sector, and briefly discuss some phenomenological aspects of the model. © 2015, The Author(s)1111Nsciescopu
General gauge symmetry in the theory and simulation of heat transport in nonsolid materials
No full textThe Green-Kubo theory of atomic heat transport relies on the ambiguous decomposition of total energy into atomicenergies of individual atoms. The challenge is to understand how the transport coefficient thermodynamically emerges from such ill-defined atomic energies. Here, we show that a simple symmetry principle for atomic energies (that is, all possible ways of distributing energy among atoms are equivalent) dictates the general theory of atomic heat transport, in which, by construction, the same heat conductivity κ is ensured regardless of the choice of atomic energies. This approach is analogous to the way in which general covariance (all coordinate systems are equivalent) is used to construct the general theory of relativity. To this end, we define atomic gauges that regulate the redundant degrees of freedom in atomic energies. The atomic gauge symmetry then uniquely determines the gauge-invariant form of macroscopic energy transfer, which is identified as heat. The gauge theory not only lays a firm foundation of the Green-Kubo formalism of heat transport, but also offers a variational method for calculating κ of nonsolid materials, as demonstrated using machine learning inferred atomic energies of Cu2S, an intriguing solid-liquid hybrid material for thermoelectrics. © 2021 American Physical Society.1

Supersymmetric clockwork axion model and axino dark matter
No full text© 2020 authors. Published by the American Physical Society. Implications of supersymmetrizing the clockwork axions are studied. Supersymmetry ensures that the saxions and axinos have the same pattern of the coupling hierarchy as the clockwork axions. If we assume supersymmetry breaking is universal over the clockwork sites, the coupling structure is preserved, while the mass orderings of the saxions and axinos can differ depending on the supersymmetry breaking scale. While the massive saxions and axions quickly decay, the lightest axino can be stable and, thus, a dark matter candidate. The relic abundance of the axino dark matter from thermal production is mostly determined by decays of the heavier axinos in the normal mass ordering. This exponentially enhances the thermal yield compared to the conventional axino scenarios. Some cosmological issues are discussed11Nsciescopu
Precision axion physics with running axion couplings
No full text© 2021, The Author(s).We study the renormalization group running of axion couplings while taking into account that the Standard Model can be extended to its supersymmetric extension at a certain energy scale below the axion decay constant. We then apply our results to three different classes of axion models, i.e. KSVZ-like, DFSZ-like, and string-theoretic axions, and examine if string-theoretic axions can be distinguished from others by having a different pattern of low energy couplings to the photon, nucleons and electron. We find that the low energy couplings of string-theoretic axions have a similar pattern as those of KSVZ-like axions but yet reveal a sizable difference which might be testable in future axion search experiments. We also note that the coupling of KSVZ-like QCD axions to the electron is dominated by a three-loop contribution involving the exotic heavy quark, gluons, top quark and Higgs field.11Nsciescopu
Transnational Dynamics : The Social Activism of Korean Immigrants and Their Descendants in Germany
No full textAnlässlich des 140. Jahrestages der Aufnahme diplomatischer Beziehungen zwischen Deutschland und Korea fanden zahlreiche kulturelle Veranstaltungen und akademische Diskurse statt. Seit 1883 haben sich die bilateralen Beziehungen über die wirtschaftliche Ebene hinaus zu einem umfassenden politischen, kulturellen und gesellschaftlichen Austausch entwickelt. Vor diesem Hintergrund rücken in diesem Sonderheft Jaok Kwon und Sang-Hui Nam die bislang in der deutsch-koreanischen Einwanderungsgeschichte wenig beleuchtete Rolle der koreanischen Migrantenbewegung in Deutschland in den Fokus. Dabei wird die Transnationalität des sozialen Aktivismus koreanischer Immigranten aus soziologischer Perspektive analysiert. Sowohl die historische Bedeutung der Akteure als auch die Wechselwirkungen sozialer Bewegungen werden im Hinblick auf den Transnationalismus untersucht
750 GeV diphoton resonance and electric dipole moments
Get PDFWe examine the implication of the recently observed 750 GeV diphoton excess for the electric dipole moments of the neutron and electron. If the excess is due to a spin zero resonance which couples to photons and gluons through the loops of massive vector-like fermions, the resulting neutron electric dipole moment can be comparable to the present experimental bound if the CP-violating angle α in the underlying new physics is of O(10−1). An electron EDM comparable to the present bound can be achieved through a mixing between the 750 GeV resonance and the Standard Model Higgs boson, if the mixing angle itself for an approximately pseudoscalar resonance, or the mixing angle times the CP-violating angle α for an approximately scalar resonance, is of O(10−3). For the case that the 750 GeV resonance corresponds to a composite pseudo-Nambu–Goldstone boson formed by a QCD-like hypercolor dynamics confining at ΛHC, the resulting neutron EDM can be estimated with α∼(750 GeV/ΛHC)2θHC, where θHC is the hypercolor vacuum angle.
