Lattice QCD and Baryon-Baryon Interactions: HAL QCD Method

open access: yesFrontiers in Physics, 2020
In this article, we review the HAL QCD method to investigate baryon-baryon interactions, such as nuclear forces in lattice QCD. We first explain our strategy in detail to investigate baryon-baryon interactions by defining potentials in field theories ...

Branching fractions of B meson decays in Mesogenesis

open access: yesJournal 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.

Baryon decays to purely baryonic final states [PDF]

open access: yesScientific Reports, 2019
AbstractThe LHCb collaboration has presented first experimental evidence that spin-carrying matter and antimatter differ. The study looked at four-body decays of the $${{\boldsymbol{\Lambda }}}_{{\boldsymbol{b}}}^{{\bf{0}}}$$ Λ

Evolution of Baryon-Free Matter Produced in Relativistic Heavy-Ion Collisions

open access: yes, 2003
A 3-fluid hydrodynamic model is introduced for simulating heavy-ion collisions at incident energies between few and about 200 AGeV. In addition to the two baryon-rich fluids of 2-fluid models, the new model incorporates a third, baryon-free (i.e.

Baryon Number Fluctuation and the Quark-Gluon Plasma [PDF]

open access: yes, 2001
We show that $\omega_B$ or $\omega_{\bar B}$, the squared baryon or antibaryon number fluctuation per baryon or antibaryon, is a possible signature for the quark-gluon plasma that is expected to be created in relativistic heavy ion collisions, as it is a

Recent Developments in Degenerate Higher Order Scalar Tensor Theories

open access: yesAnnalen der Physik, Volume 537, Issue 2, February 2025.
Degenerate Higher Order Scalar Tensor theories are reviewed, together with their applications in cosmology and astrophysics. These theories have been applied to build models of the early universe, in the description of the late‐time cosmic acceleration, as well as in astrophysics, including black hole physics. They have the potential to provide answers

From Tetraquark to Hexaquark: A Systematic Study of Heavy Exotics in the Large $N_c$ Limit [PDF]

open access: yes, 1994
A systematic study of multiquark exotics with one or $N_c-1$ heavy quarks in the large $N_c$ limit is presented. By binding a chiral soliton to a heavy meson, either a normal $N_c$-quark baryon or an exotic $(N_c+2)$-quark baryon is obtained.

A Brief, Biased View of Neutron Star Cooling

open access: yesAstronomische Nachrichten, Volume 346, Issue 1, January 2025.
ABSTRACT This is a concise and non‐technical review of topics related to neutron star (NS) cooling, for both young NSs and NSs in low‐mass x‐ray binaries. Neutrino emission from the NS core drives cooling rates, via different processes including Urca processes and pair breaking and formation at the neutron superfluid critical temperature.

Towards baryon-baryon scattering in manifestly Lorentz-invariant formulation of SU(3) baryon chiral perturbation theory

open access: yesPhysics Letters B, 2019
We study baryon-baryon scattering by applying time-ordered perturbation theory to the manifestly Lorentz-invariant formulation of SU(3) baryon chiral perturbation theory.

Baryonic content of the pion

open access: yesPhysics Letters B, 2021
The baryon form factor of charged pions arises since isospin symmetry is broken. We obtain estimates for this basic property in two phenomenological ways: from simple constituent quark models with unequal up and down quark masses, and from fitting to e+e−
