New mass limit of a strange star admitting a colour flavor locked equation of state
European Physical Journal C: Particles and Fields, 2023 A class of strange stars is analysed in the present article in hydrostatic equilibrium, whose state is defined by a CFL phase equation of state. We have compared our results with those obtained from the MIT equation of state for strange quark matter ...

, 2009 We perform an O(alpha_s^2) perturbative calculation of the equation of state of cold but dense QCD matter with two massless and one massive quark flavor, finding that perturbation theory converges reasonably well for quark chemical potentials above 1 GeV.

Update on the physics of light pseudoscalar mesons [PDF]
, 2006 We present an update of the MILC investigation of the properties of light pseudoscalar mesons using three flavors of improved staggered quarks. Results are presented for the $\pi$ and $K$ leptonic decay constants, the CKM matrix element $V_{us}$, the up,

Ds+ -- Ds- Asymmetry in Photoproduction [PDF]
, 2005 Considering of the possible difference in strange and antistrange quark distributions inside nucleon, we investigate the Ds+ -- Ds- asymmetry in photoproduction in the framework of heavy-quark recombination mechanism.

Strange matter with effective quark masses [PDF]
Journal of Physics G: Nuclear and Particle Physics, 1997 The properties of strange quark matter at zero temperature are investigated including medium effects. The quarks are considered as quasiparticles which acquire an effective mass generated by the interaction with the other quarks of the dense system. Within this approach we find that these medium effects reduce the binding energy of strange quark matter

Quark, pion and axial condensates in three-flavor finite isospin chiral perturbation theory
European Physical Journal C: Particles and Fields, 2021 We calculate the light-quark condensate, the strange-quark condensate, the pion condensate, and the axial condensate in three-flavor chiral perturbation theory ( $$\chi $$ χ PT) in the presence of an isospin chemical potential at next-to-leading order at

Enhancement of singly and multiply strangeness in p-Pb and Pb-Pb collisions at 158A GeV/c [PDF]
, 1999 The idea that the reduction of the strange quark suppression in string fragmentation leads to the enhancement of strange particle yield in nucleus-nucleus collisions is applied to study the singly and multiply strange particle production in p-Pb and Pb ...
