Search for dark photons in heavy‐ion collisions
Astronomische Nachrichten, Volume 344, Issue 1-2, January-February 2023., 2023 Abstract The vector U‐bosons, or so‐called “dark photons,” are one of the possible candidates for the dark matter mediators. They are supposed to interact with the standard matter via a “vector portal” due to the U(1)−U(1)′$$ U(1)-U{(1)}^{\prime } $$ symmetry group mixing which might make them visible in particle and heavy‐ion experiments.

Theoretical and Experimental Challenges in the Measurement of Neutrino Mass
Advances in High Energy Physics, Volume 2023, Issue 1, 2023., 2023 Neutrino masses are yet unknown. We discuss the present state of effective electron antineutrino mass from β decay experiments; effective Majorana neutrino mass from neutrinoless double‐beta decay experiments; neutrino mass squared differences from neutrino oscillation: solar, atmospheric, reactor, and accelerator‐based experiments; sum of neutrino ...

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.

Isospin-symmetry breaking in kaon production: The role of charge-symmetry [PDF]
EPJ Web of ConferencesAn excess of charged versus neutral kaons has been recently reported by the NA61/SHINE collaboration. Similar excesses were also present in previous experiments, even if with larger errors.

Recent results on Kaon Physics at KLOE-2 [PDF]
EPJ Web of Conferences, 2019 KLOE-2 extends the physics program of the forerunner KLOE experiment, especially in the field of discrete symmetries tests with neutral kaons. KLOE and KLOE-2 have collected together the largest sample of electron-positron collisions at an energy equal ...

EPJ Featured Talk: First direct measurement of radial flow in heavy-ion collisions with ALICE [PDF]
EPJ Web of ConferencesThis work presents measurements of the transverse-momentum-dependent observable v0(pT) as a novel probe of radial expansion dynamics in Pb-Pb collisions at √sNN = 5.02 TeV with the ALICE detector. Results are reported for inclusive charged hadrons, pions,

New bounds on axion-like particles from MicroBooNE
Journal of High Energy Physics, 2022 Neutrino experiments lie at the edge of the intensity frontier and therefore can be exploited to search for new light particles weakly coupled to the visible sector.

Kaon-nucleus Drell-Yan processes and kaon structure functions [PDF]
Physics Letters B, 1996 We investigate the information which could be obtained from Drell-Yan processes with sufficiently intense beams of charged kaons on isoscalar targets. It is found that combinations of $K^+$ and $K^-$ Drell-Yan measurements on isoscalar nuclear targets would allow one to extract the kaon sea quark distributions.
