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 .

Predators and scavengers: Polar bears as marine carrion providers

Oikos, Volume 2026, Issue 1, January 2026.
Scavenging is a foraging strategy widely used across the animal kingdom and apex predators provide a large amount of energy in a food web by provisioning carrion. In the harsh environmental conditions of the Arctic, apex predators such as polar bears Ursus maritimus can provide scavenging opportunities for many species. Carrion can act as a buffer when

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.

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

RIGIDLY ROTATING STRANGE QUARK STARS

International Journal of Modern Physics D, 2005
In this article, we study rotating strange quark stars in the context of general relativity. For this purpose we consider perfect fluid model composed of strange quark matter with electromagnetic field in the Gödel Universe which has rigid rotation. We solve Einstein's field equations by using equation of state for strange quark matter.

The Purely Leptonic and Semileptonic Decays of Ds∗ Meson

Advances in High Energy Physics, Volume 2026, Issue 1, 2026.
With the potential prospects of the Ds∗ at high‐luminosity heavy‐flavor experiments in the future, we investigated the CKM‐favored and tree‐dominated leptonic Ds∗⟶ℓν¯ℓ,ℓ=e,μ,τ and semileptonic Ds∗⟶Mℓ′ν¯ℓ′ M=ϕ,η′,K and ℓ′=e,μ weak decays in the standard model (SM).

Strange matter in compact stars

EPJ Web of Conferences, 2018
We discuss possible scenarios for the existence of strange matter in compact stars. The appearance of hyperons leads to a hyperon puzzle in ab-initio approaches based on effective baryon-baryon potentials but is not a severe problem in relativistic mean ...

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

Extraction of Effective Parameters From Transverse Momentum Spectra of Heavy Quarkonia in Proton–Proton Collisions at the LHC

Advances in High Energy Physics, Volume 2026, Issue 1, 2026.
The effective string tension (κ) in the Schwinger mechanism and the effective temperature (T) in Bose–Einstein statistics are extracted from the transverse momentum (pT) spectra of heavy quarkonia produced in proton‐proton (p + p) collisions at the Large Hadron Collider (LHC).

Inverse moment of the B s -meson distribution amplitude from QCD sum rule

Journal of High Energy Physics, 2020
We derive a QCD sum rule for the inverse moment of the B s -meson light-cone distribution amplitude in HQET. Within this method, the SU(3) f l symmetry violation is traced to the strange quark mass and to the difference between strange and nonstrange ...
