SUSY scenarios according to EWSB
No full textThis talk provides a limited review of SUSY scenarios with the focus on the way electroweak symmetry breaking is achieved and understood under different assumptions. Various aspects of naturalness and their implications are discussed and compared
Tax Reform in Slovakia
No full textThe paper evaluates recent tax legislation in Slovakia, effected January 2004, according to principles of optimal taxation and optimal tax systems. The author evaluates Slovak tax reform with particular regard to personal income tax and commodity taxes. The adoption of a flat personal-income-tax rate and a uniform VAT rate is viewed as in line with the optimal taxation theory, and the projected lessening of administrative costs and degree of tax evasion is positively evaluated.tax reform; flat tax; Slovakia
Radovan Nikšić: Karlovac - Projects and Realizations; Luka Krmpotić, author of the exhibition
No full textThe exhibition under the title “Radovan Nikšić: Karlovac - Projects and Realizations” was mounted by the architect Luka Krmpotić on the occasion of the hundredth anniversary of Nikšić’s birth. Radovan Nikšić, Ph.D., the university professor and member of Academy, born in Karlovac, was one of the renowned and most prominent figures of the 20th century Croatian architecture. This exhibition offered an overview of the relatively unknown segment of Nikšić’s architectural work, the one related to the architecture of Karlovac. A range of projects were displayed on this occasion: the designs for 11 residential buildings from the 1950s: residential buildings built for the needs of the Military Post, a residential complex in Kurelčeva St., the competition entry for the Gym Park (1953), a residential building (1954), the design for the Yugoslav Army Centre (1960) and the competition entry for the City Library “Ivan Goran Kovačić” (1971)

Muon g-2 and other observables in models with extended Higgs and matter sectors
No full textI review possible explanations of the muon g-2 anomaly in models with
extended Higgs and matter sectors, focusing on extensions of the standard model
and the two Higgs doublet model with vectorlike leptons. Predictions of these
models, namely the modifications of muon Yukawa and gauge couplings, that can
be searched for at the LHC and future colliders, are summarized. I also discuss
striking predictions for di-Higgs and tri-Higgs signals at a muon collider that
can be tested even at very low energies. Furthermore, I briefly comment on
other interesting features and signatures of models with extended Higgs sector
and vectorlike matter.Comment: 5 pages, 6 figures, contribution to the proceedings of the 20th

Hidden Higgs Scenarios: new constraints and prospects at the LHC
No full textWe review the motivation for hidden Higgs scenarios and discuss the light CP odd Higgs scenario in the NMSSM as an example. We summarize experimental constraints including recent limits from BaBar and Aleph. The main part of the talk is the discussion of dominant decay modes of the standard model like Higgs boson, and related decay modes of the charged Higgs and heavy CP even Higgs bosons, in these scenarios with the focus on signatures and prospects for the LHC. Examples include the direct production of a light CP odd Higgs boson, and a light charged Higgs boson in top quark decays
Loop suppressed electroweak symmetry breaking and naturally heavy superpartners
No full textA model is presented in which O(10 TeV) stop masses, typically required by the Higgs boson mass in supersymmetric models, do not originate from soft supersymmetry breaking terms that would drive the Higgs mass squared parameter to large negative values but rather from the mixing with vectorlike partners. Their contribution to the Higgs mass squared parameter is reduced to threshold corrections and, thus, it is one loop suppressed compared to usual scenarios. New fermion and scalar partners of the top quark with O(10 TeV) masses are predicted
