Strange quark matter

Nuclear Physics A, 1995
Abstract Several experiments are using heavy ion collisions as a means of creating and studying strange quark matter in the laboratory. I will describe why I think it is important and interesting to look for strange quark matter, and discuss the physics addressed by the experiments that have been designed to look for it in high energy heavy ion ...

Is distinct location evidence of distinct objects? Multilocation and the problem of parsimony

Analytic Philosophy, Volume 66, Issue 3, Page 394-401, September 2025.
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.

A Relativistic Compact Stellar Model of Anisotropic Quark Matter Mixed with Dark Energy

Advances in High Energy Physics, 2021
The possibility of strange stars mixed with dark energy to be one of the candidates for dark energy stars is the main issue of the present study. Our investigation shows that quark matter atcs as dark energy after a certain yet unknown critical condition

Treatment of broken symmetry in the Faddeev approach to the strange baryon spectra

, 2012
By solving the Faddeev equations we calculate the mass of the strange baryons in the framework of a relativistic constituent quark model. The Goldstone-boson-exchange quark-quark interaction is derived from $SU(3)_F$ symmetry, which is explicitly broken ...

$D_s$ Asymmetry in Photoproduction [PDF]

, 2005
By adopting two models of strange and antistrange quark distributions inside nucleon, the light-cone meson-baryon fluctuation model and the effective chiral quark model, we calculate the $D_s^+ - D_s^-$ asymmetry in photoproduction in the framework of ...

The Curious Concept That Almost Nobody Seemed to Care About at First: Virtual Particles in the Post‐War Period**

Berichte zur Wissenschaftsgeschichte, Volume 48, Issue 1-2, Page 143-162, August 2025.
Abstract Short‐lived, unobservable, and not subject to the usual rules of conservation of energy and momentum, virtual particles—an integral part of the conceptual framework of quantum field theory (QFT)—exhibit a number of curious characteristics which, in recent decades, have in part fueled important discussions about their ontological status ...

Recent results from the G0 experiment

EPJ Web of Conferences, 2010
We have measured parity violating asymmetries in elastic electron-proton and quasi-elastic electrondeuteron scattering at backward electron angle. These measurements have been done at two momentum transfers : Q2 = 0.22 and 0.63 (GeV/c)2 .

Human flaws and logical tools in engineering

The Canadian Journal of Chemical Engineering, Volume 103, Issue 8, Page 3512-3520, August 2025.
Abstract This paper explores the limitations of human cognition, especially in engineering research, emphasizing the need for mathematical models and methods to guide decision‐making and theory validation. While human cognition excels in certain tasks, it is prone to biases that can distort our understanding.

A strange contribution to the neutron EDM

Journal of High Energy Physics
We analyze the contribution of hypothetical quark electric dipoles to the electric dipole moment (EDM) of the neutron. Particular emphasis is devoted to the strange quark contribution.

Hot and dense pQCD in a very strong magnetic background [PDF]

EPJ Web of Conferences
We compute the pressure, chiral condensate and strange quark number susceptibility from perturbative QCD up to two-loop order at finite temperature and very high magnetic fields with physical quark masses. We also discuss the case of cold and dense quark
