The Phase Diagram of High Temperature QCD with Three Flavors of Improved Staggered Quarks

open access: yes, 2003
We report on progress in our study of high temperature QCD with three flavors of improved staggered quarks. Simulations are being carried out with three degenerate quarks with masses less than or equal to the strange quark mass, $m_s$, and with ...

Seismic search for strange quark nuggets

open access: yesPhysical Review D, 2006
Bounds on masses and abundances of Strange Quark Nuggets (SQNs) are inferred from a seismic search on Earth. Potential SQN bounds from a possible seismic search on the Moon are reviewed and compared with Earth capabilities. Bounds are derived from the data taken by seismometers implanted on the Moon by the Apollo astronauts.

Stable strange quark matter objects with running masses and coupling constant

open access: yesNuclear Physics B, 2017
We improve our recently proposed unified description for strange quark matter (SQM) objects, in the way that analytical expressions are derived and used to calculate the distribution of particles inside an SQM object.

Hawking-Unruh Hadronization and Strangeness Production in High Energy Collisions

open access: yesAdvances in High Energy Physics, 2014
The thermal multihadron production observed in different high energy collisions poses many basic problems: why do even elementary, e+e- and hadron-hadron, collisions show thermal behaviour?

Nucleon strangeness polarization from $$\varLambda /\bar{\varLambda }$$ Λ/Λ¯ hyperon production in polarized proton–proton collision at RHIC

open access: yesEuropean Physical Journal C: Particles and Fields, 2019
We calculate the inclusive production of a polarized $$\varLambda $$ Λ or $$\bar{\varLambda }$$ Λ¯ hyperon from the single longitudinally polarized proton and proton (pp) collision at RHIC.

Strange quark matter with effective quark masses

open access: yes, 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

Revisiting Scalar and Pseudoscalar Couplings with Nucleons

open access: yes, 2012
Certain dark matter interactions with nuclei are mediated possibly by a scalar or pseudoscalar Higgs boson. The estimation of the corresponding cross sections requires a correct evaluation of the couplings between the scalar or pseudoscalar Higgs boson ...
