Heavy - light flavor correlations of anisotropic flows at LHC energies within event-by-event transport approach

open access: yesPhysics Letters B, 2020
The heavy quarks (HQs) are a unique probe of the hot QCD matter properties and their dynamics are coupled to the locally thermalized expanding quark gluon plasma.

Two Micron‐Size Dark Dimensions

open access: yesFortschritte der Physik, Volume 73, Issue 8, August 2025.
Abstract Two extra dimensions of micron scale might simultaneously address the gauge and cosmological hierarchy problems. In this paper various observational bounds in scenarios with one and two large extra dimensions are examined, to see if they are compatible with the micron scale.

Master formula for twist-3 soft-gluon-pole mechanism to single transverse-spin asymmetry

open access: yes, 2007
Perturbative QCD relates the single transverse-spin asymmetries (SSAs) for hard processes at large transverse-momentum of produced particle to partonic matrix elements that describe interference between scattering from a coherent quark–gluon pair and ...

Characterizing the initial conditions of heavy-ion collisions at the LHC with mean transverse momentum and anisotropic flow correlations

open access: yesPhysics Letters B, 2022
Correlations between mean transverse momentum [pT] and anisotropic flow coefficients v2 or v3 are measured as a function of centrality in Pb–Pb and Xe–Xe collisions at sNN=5.02 TeV and 5.44 TeV, respectively, with ALICE.

Maximum Mass Limit of Generalized MIT Compact Star: A Theoretical Study of Thin Shell Dynamics and Gravitational Lensing

open access: yesFortschritte der Physik, Volume 73, Issue 8, August 2025.
Abstract In this study, the properties, equilibrium, and stability of compact objects within the framework of teleparallel gravity with the generalized MIT bag model are investigated. By incorporating the modified field equations, the influence of the generalized bag constant on the structure and physical characteristics of quark stars and neutron ...

A CGC/saturation approach for angular correlations in proton–proton scattering

open access: yesEuropean Physical Journal C: Particles and Fields, 2017
We generalized our model for the description of hard processes, and calculate the value of the azimuthal angular correlations (Fourier harmonics $$v_n$$ v n ), for proton–proton scattering.

The transverse nucleon single-spin asymmetry for the semi-inclusive production of photons in lepton-nucleon scattering

open access: yesPhysics Letters B, 2020
We study the semi-inclusive production of real, high-pT, isolated photons in unpolarized and polarized lepton-proton collisions, ℓp→ℓγX. In particular we analyze the transverse nucleon single-spin asymmetry within the collinear twist-3 formalism in ...

Yoctosecond Metrology Through Hanbury Brown–Twiss Correlations from a Quark-Gluon Plasma [PDF]

open access: yesPhysical Review Letters, 2012
Expansion dynamics at the yoctosecond time scale affect the evolution of the quark gluon plasma (QGP) created in heavy ion collisions. We show how these dynamics are accessible through Hanbury Brown-Twiss (HBT) intensity interferometry of direct photons emitted from the interior of the QGP.

Generation of Electric Current by Magnetic Field at the Boundary: Quantum Scale Anomaly Versus Semiclassical Meissner Current Outside of the Conformal Limit

open access: yesAdvanced Physics Research, Volume 4, Issue 7, July 2025.
The paper discusses the role of scale anomaly in generating edge electric currents via the scale magnetic effect in scalar electrodynamics. Although the boundary electric current is much weaker than the Meissner current induced in superconducting materials, the scale anomaly can enhance conductivity near the boundary of the material.
