Baryon-to-Meson Ratios in Jets from Au+Au and p+p Collisions at 200 GeV
Experimental results from RHIC and the LHC reveal a significant enhancement in baryon-to-meson yield ratios at intermediate $p_{\rm{T}}$ in high-energy nuclear collisions relative to $p$+$p$ collisions.

Supersymmetry Breaking: Models of Gauge Mediation with Gauge Messengers [PDF]
, 2010 With the start of the LHC, it becomes increasingly important to understand the experimental signatures that discriminate different extensions of the standard model. Supersymmetry (SUSY), in particular the Minimal Supersymmetric Standard Model (MSSM),

Calm Multi-Baryon Operators [PDF]
, 2017 Outstanding problems in nuclear physics require input and guidance from lattice QCD calculations of few baryons systems. However, these calculations suffer from an exponentially bad signal-to-noise problem which has prevented a controlled extrapolation ...

Fortschritte der Physik, Volume 73, Issue 3, March 2025.Abstract Current observations show that a significant fraction of the Universe is composed of dark energy and dark matter. In this paper, the simultaneous effects of these dark sectors on the Euler–Heisenberg black hole are investigated, using the quintessence matter field and perfect fluid to model them. In particular, the black hole's thermodynamics,

Meson baryon components in the states of the baryon decuplet [PDF]
, 2014 We extend the Weinberg compositeness condition to partial waves of L = 1 and resonant states to determine the weight of meson-baryon component in the Jp = 3+/2 baryon decuplet.

Recent results of Baryon electromagnetic form factors at BESIII [PDF]
EPJ Web of ConferencesBaryon Electromagnetic Form Factors are essential for testing ground state models of nucleon internal structures. At the BESIII experiment, a comprehensive study has been conducted on the electromagnetic form factors of various baryons.

Visible GeV ALP from TeV Vector‐Like Leptons
Fortschritte der Physik, Volume 73, Issue 3, March 2025.Abstract A model is presented where a GeV axion‐like‐particle (ALP) is predicted in a large portion of the parameter space due to the presence of explicit Peccei–Quinn (PQ) symmetry‐breaking terms in an exotic leptonic sector. The latter provides a solution to the muon g−2$g-2$ anomaly, within the framework of the Linear Seesaw neutrino mechanism.

Lattice QCD and Baryon-Baryon Interactions: HAL QCD Method
Frontiers 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 ...
