Branching fractions of B meson decays in Mesogenesis
Journal of High Energy Physics, 2023 Production of the matter-antimatter asymmetry in the B-Mesogenesis mechanism is directly related to the branching fraction of seemingly baryon number violating decays of B mesons into a light Standard Model baryon and missing energy.

Baryons 2002, 2003 We review the status of hybrid baryons. The only known way to study hybrids rigorously is via excited adiabatic potentials. Hybrids can be modelled by both the bag and flux-tube models. The low-lying hybrid baryon is N 1/2^+ with a mass of 1.5-1.8 GeV. Hybrid baryons can be produced in the glue-rich processes of diffractive gamma N and pi N production,

Physik in unserer Zeit, Volume 56, Issue 1, Page 30-37, January 2025.Galaxien wie die Milchstraße sind umhüllt von einem gigantischen Kokon aus diffusem Gas. Aktuelle Forschungsergebnisse belegen, dass dieses zirkumgalakische Medium eine entscheidende Rolle für die Entstehung und Entwicklung von Galaxien spielt. Zusammenfassung Als zirkumgalaktisches Medium bezeichnet man die gasförmigen Hüllen von Galaxien, die sich ...

Gravitational baryogenesis in non-minimal kinetic coupling model
European Physical Journal C: Particles and Fields, 2023 In this work, we consider the gravitational baryogenesis in the framework of non-minimal derivative coupling model. A mechanism to generate the baryon asymmetry based on the coupling between the derivative of the Ricci scalar curvature and the baryon ...

Advances in Mathematical Physics, Volume 2025, Issue 1, 2025.Lorentz transformations are central to relativistic mechanics, explaining phenomena such as the mass–energy relationship, spatial contraction, momentum transformation, velocity addition, and the geometric structure of Minkowski space‐time. While traditionally derived for motion along a single spatial axis, these transformations can be generalized to ...

The imprint of conservation laws on correlated particle production
Journal of High Energy PhysicsThe study of event-by-event fluctuations of net-baryon number in a subspace of full phase space is a promising direction for deciphering the structure of strongly interacting matter created in collisions of relativistic heavy nuclei.

Tensor Condensate Accompanied by Chiral Transition in a Strong Magnetic Field
Advances in High Energy Physics, Volume 2025, Issue 1, 2025.We investigate tensor condensates and chiral condensates in the (2 + 1)‐flavor Nambu–Jona–Lasinio model at finite temperature and density in the presence of a strong magnetic field. The emergence of the tensor condensate is attributed to the four‐fermion interaction.

Heavy Quarkonium States With Baryonic Chemical Potential
Advances in High Energy Physics, Volume 2025, Issue 1, 2025.In this work, we have studied the dissociation behavior of 1S and 2S states of quarkonium using quasiparticle approach where the Debye mass depends on baryonic chemical potential. The binding energies of the quarkonium states has been obtained by using quasiparticle Debye mass which further depends on temperature and baryonic chemical potential (μb ...

On Extracting Thermal Parameters and Scenario in High‐Energy Collisions
Advances in High Energy Physics, Volume 2025, Issue 1, 2025.The inconsistent thermal parameters derived from various models in high‐energy collisions are examined. A comprehensive literature review suggests model‐independent parameters to address these inconsistencies, based on the average transverse momentum 〈pT〉 and root‐mean‐square transverse momentum pT2.

Beam energy dependence of net-hyperon yield and its implication on baryon transport mechanism
Physics Letters BIn the constituent quark model, each quark inside a baryon carries 1/3 unit of the baryon number. An alternative picture exists where the center of a Y-shaped topology of gluon fields, called the baryon junction, carries a unit baryon number.
