Discriminating hadronic and quark stars through gravitational waves of fluid pulsation modes [PDF]
We investigate non-radial oscillations of hadronic, hybrid and pure self-bound strange quark stars with maximum masses above the mass of the recently observed massive pulsars PSR J1614-2230 and PSR J0348-0432 with $M \approx 2 M_{\odot}$.

Radial stability of anisotropic strange quark stars [PDF]
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
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
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 ...

Effects of density-dependent quark mass on phase diagram of three-flavor quark matter
Considering the density dependence of quark mass, we investigate the phase transition between the (unpaired) strange quark matter and the color-flavor-locked matter, which are supposed to be two candidates for the ground state of strongly interacting ...

Light Quark Masses with Dynamical Wilson Fermions [PDF]
We determine the masses of the light and the strange quarks in the $\bar{MS}$-scheme using our high-statistics lattice simulation of QCD with dynamical Wilson fermions. For the light quark mass we find $m^{light}_{\bar{MS}}(2 GeV) = 2.7(2) MeV$, which is

Searching for Strange Quark Matter Objects in Exoplanets [PDF]
The true ground state of hadronic matter may be strange quark matter (SQM). Consequently, observed pulsars may actually be strange quark stars, but not neutron stars.

Is distinct location evidence of distinct objects? Multilocation and the problem of parsimony
Abstract For an object to be multilocated is for it to wholly occupy disjoint spatial regions simultaneously. If multilocation is possible, it is possible that a multilocated particle is wholly located at 1080 distinct locations, such that it constitutes a particle‐for‐particle duplicate of the actual universe.

Properties of strange quark stars with isovector interactions
We study the properties of strange quark stars by employing a 3-flavor Nambu-Jona-Lasinio model with both scalar-isovector and vector-isovector interactions.
