Weak kaon production off the nucleon and Watson's theorem

Physics Letters B, 2021
We have improved the tree-level model of Ref. [1] for weak production of kaons off nucleons by partially restoring unitarity. This is achieved by imposing Watson's theorem to the dominant vector and axial-vector contributions in appropriate angular ...

Role of the Coulomb interaction in the flow and the azimuthal distribution of kaons from heavy ion reactions [PDF]

, 1997
Coulomb final-state interaction of positive charged kaons in heavy ion reactions and its impact on the kaon transverse flow and the kaon azimuthal distribution are investigated within the framework of QMD (Quantum Molecular Dynamics) model.

Extension of the axiomatic analyticity domain: Kaon-Kaon and Pion-Kaon scattering [PDF]

Il Nuovo Cimento A Series 10, 1967
In this paper we collect some extended domains of validity of dispersion relations for the reactions K + K → K + K, K +\(\bar K\) → K +\(\bar K\), K +\(\bar K\) →\(\bar K\) + K, π + K → π + K, π + K → K + π, K +\(\bar K\) → π + π. The results are shown in Fig. 3, 4 and 8.

Role of quark-interchange processes in evolution of mesonic matter

, 2011
We divide the cross section for a meson-meson reaction into three parts. The first part is for the quark-interchange process, the second for quark-antiquark annihilation processes and the third for resonant processes.

Bose-Einstein Correlations of Charged Kaons in Central Pb+Pb Collisions at $E_{beam} = 158 AGeV$ [PDF]

, 2002
Bose-Einstein correlations of charged kaons were measured near mid-rapidity in central Pb+Pb collisions at 158 A$\cdot$GeV by the NA49 experiment at the CERN SPS.

Subthreshold ϕ meson production in nucleus-nucleus collisions

EPJ Web of Conferences, 2014
Part of emission of the negatively charged kaons from the nucleus-nucleus collisions appears to originate from decays of ϕ(1020) mesons into the K+K− channel.

Analytical Description of the Distributions of Primary and Secondary Cosmogenic Particles

Advances in High Energy Physics, Volume 2026, Issue 1, 2026.
In this work, we present an analytical description of the energy distributions of primary and secondary cosmogenic particles on Earth in terms of parameters having clear physical meaning. A modified power law is assumed for energy distributions, incorporating terms such as energy loss/decay, which are effective at low energies, and a source term, which
