Magnetized strange quark model with Big Rip singularity in f(R, T) gravity [PDF]
, 2017 Locally rotationally symmetric (LRS) Bianchi type-I magnetized strange quark matter (SQM) cosmological model has been studied based on f(R, T) gravity.

Searching For Strange Quark Planets [PDF]
arXiv, 2021 Strange quark matter (SQM) may be the true ground state of matter. According to this SQM hypothesis, the observed neutron stars actually should all be strange quark stars. But distinguishing between neutron stars and strange quark stars by means of obser- vations is extremely difficult.
arxiv
J.Phys. G30 (2004) S725-S734, 2004 The paper provides a short report on strangeness production in ultrarelativistic nucleus-nucleus collision, with the main stress on strange particle abundances.

Strong and Weak Interactions of Strange Hadrons [PDF]
Prog.Theor.Phys.Suppl.120:95-110,1995, 1995 I review hadronic processes involving strange hadrons, especially hyperons from the quark structure point of view. The strong interaction of quarks expects several important new features when the strangeness is introduced upon the non-strange degrees of freedom.

Consistency between SU(3) and SU(2) covariant baryon chiral perturbation theory for the nucleon mass
Physics Letters B, 2017 Treating the strange quark mass as a heavy scale compared to the light quark mass, we perform a matching of the nucleon mass in the SU(3) sector to the two-flavor case in covariant baryon chiral perturbation theory.

Lattice simulations with $N_f=2+1$ improved Wilson fermions at a fixed strange quark mass [PDF]
, 2016 The explicit breaking of chiral symmetry of the Wilson fermion action results in additive quark mass renormalization. Moreover, flavour singlet and non-singlet scalar currents acquire different renormalization constants with respect to continuum ...

Radial stability of anisotropic strange quark stars [PDF]
, 2016 The influence of the anisotropy in the equilibrium and stability of strange stars is investigated through the numerical solution of the hydrostatic equilibrium equation and the radial oscillation equation, both modified from their original version to ...

Heavy hadrons spectra on lattice using NRQCD
EPJ Web of Conferences, 2018 Comparison of radial excitation energies to masses show that the velocity of b quark is very non-relativistic in bottomonium states. In a mixed system like charmed B meson, the b quark has less velocity than it has in bottomonium states and in strange B ...

Electric transitions of the charmed-strange mesons in a relativistic quark model
European Physical Journal C: Particles and Fields, 2020 In the present work, we adopt a relativistic constituent quark model to depict the charmed strange meson spectroscopy, in which $$D_{s0}(2317)$$ Ds0(2317) and $$D_{s1}(2460)$$ Ds1(2460) are considered as the $$1^3P_0$$ 13P0 and $$1P_1^\prime $$ 1P1 ...

Strangeness in the Nucleon [PDF]
AIPConf.Proc.939:3-6,2007, 2007 There are several different experimental indications, such as the strangeness contribution to the magnetic moment of the proton, sigma_{\pi N} term, strange spin polarization, ratio of strange and non strange quark flavor distributions which suggest that the nucleon contains a hidden strangeness component which is contradictory to the naive constituent
