Particles, 2022 High-energy heavy-ion collisions offer the unique possibility to study fundamental properties of nuclear matter in the laboratory, which are relevant for our understanding of the structure of compact stellar objects and the dynamics of neutron star ...

Probing Dense Nuclear Matter in the Laboratory: Experiments at FAIR and NICA
Universe, 2021 The poorly known properties of high-density strongly-interacting matter govern the structure of neutron stars and the dynamics of neutron star mergers. New insight has been and will be gained by astronomical observations, such as the measurement of mass ...

Particle Ratios in a Multicomponent Nonideal Hadron Resonance Gas
Advances in High Energy Physics, Volume 2023, Issue 1, 2023., 2023 We have considered formation of a multicomponent nonideal hot and dense gas of hadronic resonances in the ultrarelativistic heavy ion collisions. In the statistical thermal model approach, the equation of state (EoS) of the noninteracting ideal hadron resonance gas (IHRG) does not incorporate either the attractive part or the short‐range repulsive part

Possible Dark Matter Annihilation Signal in the AMS-02 Antiproton Data. [PDF]
Physical Review Letters, 2016 Using the latest AMS-02 cosmic-ray antiproton flux data, we search for a potential dark matter annihilation signal. The background parameters about the propagation, source injection, and solar modulation are not assumed a priori but based on the results ...

Observation of Antiprotons [PDF]
Physical Review, 1955 One of the striking features of Dirac's theory of the electron was the appearance of solutions to his equations which required the existence of an antiparticle, later identified as the positron.

Charge‐State Distributions of Highly Charged Lead Ions at Relativistic Collision Energies
Annalen der Physik, Volume 534, Issue 3, March 2022., 2022 Presented is a study of the charge‐state evolution of relativistic lead ions passing through a thin aluminum stripper foil allowing to store partially stripped ions in the LHC for the very first time and laying the groundwork to optimize the yields of charge states of interest for experiments within the scientific program of the future Gamma Factory ...

Expanding Nuclear Physics Horizons with the Gamma Factory
Annalen der Physik, Volume 534, Issue 3, March 2022., 2022 The Gamma Factory is an ambitious proposal for a source of photons with energies up to hundreds of MeV and photon fluxes exceeding those of the currently available gamma sources by orders of magnitude. The paper surveys the new opportunities in nuclear physics and related fields that may be afforded by the this facility. Abstract The Gamma Factory (GF)

PERSPECTIVES FOR POLARIZED ANTIPROTONS [PDF]
International Journal of Modern Physics E, 2009 In the framework of the FAIR project the PAX Collaboration has suggested new experiments using polarized protons and antiprotons. In order to provide polarized antiprotons, the proposed mechanisms for the production of a polarized stored have to be investigated.

Advances in High Energy Physics, Volume 2022, Issue 1, 2022., 2022 We collected the transverse momentum (mass) spectra of charged hadrons (π−, π+, K−, K+, p¯, and p) produced in collisions over a center‐of‐mass energy range from 2.70 to 200 GeV (per nucleon pair). The modified Tsallis–Pareto‐type function (the TP‐like function) with average transverse flow velocity is used to describe the contribution of participant ...

Color Transparency in
Physics, 2022 Exclusive channels of antiproton annihilation on the bound nucleon are sensitive to mesonic interactions with the target residue. If the hard scale is present, then such interactions should be reduced due to color transparency (CT).
