Magnetic moments of the lowest-lying singly heavy baryons
Physics Letters B, 2018 A light baryon is viewed as Nc valence quarks bound by meson mean fields in the large Nc limit. In much the same way a singly heavy baryon is regarded as Nc−1 valence quarks bound by the same mean fields, which makes it possible to use the properties of ...

Cosmological Dynamics of Interacting Dark Energy and Dark Matter in f(Q)$f(Q)$ Gravity
Fortschritte der Physik, Volume 73, Issue 5, May 2025.Abstract In this work, the behavior of interacting dark energy (DE) and dark matter (DM) within a model of f(Q)$f(Q)$ gravity is explored, employing the standard framework of dynamical system analysis. The power‐law f(Q)$f(Q)$ model is considered, incorporating two different forms of interacting DE and DM: 3αHρm$3\alpha H\rho _m$ and α3HρmρDE$\frac ...

Detecting a first-order transition in the QCD phase diagram with baryon–baryon correlations [PDF]
, 2010 We suggest baryon–baryon correlations as an experimentally accessible signature for a first-order phase transition between a baryon-rich phase, like quarkyonic, and a baryon-suppressed hadronic phase in the QCD phase diagram.

Physics Letters BAzimuthal anisotropy scaling functions are constructed from species-resolved anisotropy measurements in Pb+Pb (sNN=2.76, 5.02 TeV) and Au+Au (sNN=7.7–200 GeV) collisions to probe baryon transport and medium response at finite baryon chemical potential ...

Exploring Dark Photon Production and Kinetic Mixing Constraints in Heavy‐Ion Collisions
Astronomische Nachrichten, Volume 346, Issue 3-4, March-May 2025.ABSTRACT Vector U‐bosons, often referred to as “dark photons,” are potential candidates for mediating dark matter interactions. In this study, we outline a procedure to derive theoretical constraints on the upper bound of the kinetic mixing parameter ϵ2MU$$ {\upvarepsilon}^2\left({M}_U\right) $$ using dilepton data from heavy‐ion from SIS to RHIC ...

Baryon–Baryon interactions from lattice QCD [PDF]
Chinese Physics C, 2010 We report on new attempt to investigate baryon-baryon interactions in lattice QCD. From the Bethe-Salpeter (BS) wave function, we have successfully extracted the nucleon-nucleon ($NN$) potentials in quenched QCD simulations, which reproduce qualitative features of modern $NN$ potentials.

Quark model for baryon-baryon processes
, 1967 A quark (Q) model recently proposed by the authors for high-energy meson-baryon and photoproduction processes is extended to high-energy baryon-baryon scattering and production of negative-parity baryons.

Dark Energy From the Gravitational Wave Background With Scalar Field Dark Matter
Astronomische Nachrichten, Volume 346, Issue 3-4, March-May 2025.ABSTRACT Recent observational results, such as those from pulsar timing arrays (PTA), suggest a low‐frequency Gravitational Wave Background (GWB) permeates our universe. This opens the possibility that gravitational waves could span a broader spectrum, potentially impacting cosmological scales.

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),
