Study of the p–p–K + and p–p–K - dynamics using the femtoscopy technique
No full textThe interactions of kaons (K) and antikaons (K ̄) with few nucleons (N) were studied so far using kaonic atom data and measurements of kaon production and interaction yields in nuclei. Some details of the three-body KNN and K ̄ NN dynamics are still not well understood, mainly due to the overlap with multi-nucleon interactions in nuclei. An alternative method to probe the dynamics of three-body systems with kaons is to study the final state interaction within triplet of particles emitted in pp collisions at the Large Hadron Collider, which are free from effects due to the presence of bound nucleons. This Letter reports the first femtoscopic study of p–p–K + and p–p–K - correlations measured in high-multiplicity pp collisions at s = 13 TeV by the ALICE Collaboration. The analysis shows that the measured p–p–K + and p–p–K - correlation functions can be interpreted in terms of pairwise interactions in the triplets, indicating that the dynamics of such systems is dominated by the two-body interactions without significant contributions from three-body effects or bound states
Spherical Functions on SO0(p, q) / SO(p) × SO(q)
No full textAbstract. An integral formula is derived for the spherical functions on the symmetric space G/K = SO0(p, q) / SO(p) × SO(q). This formula allows us to state some results about the analytic continuation of the spherical functions to a tubular neighbourhood of the subalgebra a of the abelian part in the decomposition G = KAK. The corresponding result is then obtained for the heat kernel of the symmetric space SO0(p, q) / SO(p) × SO(q) using the Plancherel formula. In the Conclusion, we discuss how this analytic continuation can be a helpful tool to study the growth of the heat kernel.

measured p–p–K+ and p–p–K− correlation functions can be
interpreted in terms of pairwise interactions in the triplets,

Meson Decay in e p → e p K+ K- and e p → e p K+ K- π0 events
No full textabstract: In the quark model, meson states consisting of a quark/anti-quark pair must obey Poincaré symmetry. As a result of that symmetry, for meson total angular momentum J, parity P, and charge conjugation symmetry C, states with JPC= 0--, 0+-, 1-+, 2+-, 3-+, 4+-, … should not be observed. A meson observed experimentally with such quantum numbers would indicate a so-called “exotic� meson state. Exotic mesons can be multi-quark states like tetraquarks, a combination of two or more gluons known as glueballs, or a hybrid meson (qqg). Theories have suggested that three possible exotic meson states with the 1-+ quantum number: π1, η1, and η‘1,. However, no conclusive evidence for the existence of these three exotic states has been observed. This research will look for new states that decay to K* K final states with an emphasis on exotic mesons. An analysis of K+ K- π0 final states will be presented, where a restriction on the K - π0 invariant mass yields an unexpected enhancement in the K+ K- π0 spectrum. (abstract
Electron beam photonics in metamaterials and plasmonic nanostructures
No full textWith the advancements in electron microscopy, the spectroscopic techniques based on electron beam are widely used to get the photonic information of nanophotonic structures such as photonic crystals, metamaterials, and plasmonic nanostructures. In so doing, free electrons provide unique opportunities in pumping or probing such nanostructures with their unrivalled broadband and localized excitation capability compared to ordinary light illumination. Apart from spectroscopy, those capabilities can also enable the efficient pumping of nanophotonic structures for the generation of light in various forms. Here, we will discuss our recent efforts to pump various nanophotonic structures toward the development of nanoscale light sources [1,2]. The concept of amplifying the evanescent field of free electrons will also be discussed where it is enabled by introducing a plasmonic metal film [3] in a fiber-based geometry
