Baryon number conservation and the cumulants of the net proton distribution
, 2012 We discuss the modification of the cumulants of the net baryon and net proton distributions due to the global conservation of baryon number in heavy-ion collisions. Corresponding probability distributions and their cumulants are derived analytically.

Baryon and Lepton Number Assignment in $E_6$ Models [PDF]
, 1995 In $E_6$ models there are new particles whose baryon number is not uniquely assigned. We point out that the baryon and lepton number assignment to these particles can change the baryogenesis scenario significantly.

Fortschritte der Physik, EarlyView.Abstract The unification of conformal and fuzzy gravities with internal interactions is based on the facts that i) the tangent group of a curved manifold and the manifold itself do not necessarily have the same dimensions and ii) both gravitational theories considered here have been formulated in a gauge theoretic way.

Generation of SU(3) sum rule for charmed baryon decay
Journal of High Energy Physics, 2022 Flavor SU(3) symmetry is a powerful tool to analyze charmed baryon decays. In this work, we propose an approach to generate SU(3) sum rules for the singly and doubly charmed baryon decays without writing the Wigner-Eckhart invariants explicitly. The SU(3)

Comparable dark matter and baryon abundances with a heavy dark sector
Physics Letters B, 2023 We propose a scenario that explains the comparable abundances of dark matter (DM) and baryons without any coincidence in the corresponding particle masses.

Magnetic Hopfions as Local Rotations of the Uniform Magnetization Background
physica status solidi (RRL) – Rapid Research Letters, EarlyView.The Hopf mapping of 3D coordinate space to the unit sphere m2 = 1 in the magnetization space m(r) can be parametrized by some angles. These angles are used to define a local rotation matrix to restore the hopfion magnetization configuration from the uniformly magnetized state for any Hopf indices.

Decuplet baryon magnetic moments in a QCD-based quark model beyond quenched approximation [PDF]
, 1998 We study the decuplet baryon magnetic moments in a QCD-based quark model beyond quenched approximation. Our approach for unquenching the theory is based on the heavy baryon perturbation theory in which the axial couplings for baryon - meson and the meson-

Radial excitations of the decuplet baryons
European Physical Journal C: Particles and Fields, 2017 The ground and first excited states of the decuplet baryons are studied using the two-point QCD sum rule approach. The mass and residue of these states are computed and compared with the existing experimental data and other theoretical predictions.

QCD and e+e- --> Baryon + anti-Baryon [PDF]
, 2002 We discuss the QCD constraints on e+e- --> baryon-anti-baryon close to threshold, in light of the puzzling experimental data which indicate that close to threshold sigma (e+e- --> n n-bar) > sigma (e+e- --> p p-bar).
