Energy dependence of transverse quark flow in heavy ion collisions

, 2004
Energy dependence of quark transverse flow carries information about dynamical properties (equation of state, initial conditions) of deconfined matter produced in heavy ion collisions.

Partition Functions and Mass Action Constants of Plasmas of Light Elements at Higher Temperatures

Contributions to Plasma Physics, Volume 65, Issue 7, August 2025.
ABSTRACT We first analyze the relations between the work of Planck and Klimontovich and show that Klimontovich's kinetic theory of non‐ideal plasmas confirms Planck's partition function for the hydrogen plasma. We discuss and check the Planck‐Brillouin‐Larkin (PBL) expressions for Hydrogen with PIMC calculations and derive new partition functions and ...

The emergence of the ΔU = 0 rule in charm physics

Journal of High Energy Physics, 2019
We discuss the implications of the recent discovery of CP violation in two-body SCS D decays by LHCb. We show that the result can be explained within the SM without the need for any large SU(3) breaking effects.

QED corrections in B ¯ → K ¯ ℓ + ℓ − $$ \overline{B}\to \overline{K}{\mathrm{\ell}}^{+}{\mathrm{\ell}}^{-} $$ at the double-differential level

Journal of High Energy Physics, 2020
We present a detailed analysis of QED corrections to B ¯ → K ¯ ℓ + ℓ − $$ \overline{B}\to \overline{K}{\mathrm{\ell}}^{+}{\mathrm{\ell}}^{-} $$ decays at the double-differential level.

Heavy quarks and the collective properties of hot QCD

, 2010
After reviewing the evidence that QCD matter at ultrarelativistic energies behaves as a very good fluid, we describe the connection of QCD fluidity to heavy quark observables. We review the way in which heavy quark spectra can place tighter limits on the

Two Micron‐Size Dark Dimensions

Fortschritte 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.

Three-loop massive form factors: complete light-fermion and large-N c corrections for vector, axial-vector, scalar and pseudo-scalar currents

Journal of High Energy Physics, 2018
We compute the three-loop QCD corrections to the massive quark form factors with external vector, axial-vector, scalar and pseudo-scalar currents. All corrections with closed loops of massless fermions are included.

Heavy-light meson spectrum with and without NRQCD

, 2000
Results for the spectrum of S and P-wave charmed mesons are obtained in the quenched approximation from a tadpole-improved anisotropic gauge field action and a D234 quark action.

The dynamical diquark model: first numerical results

Journal of High Energy Physics, 2019
We produce the first numerical predictions of the dynamical diquark model of multiquark exotic hadrons. Using Born-Oppenheimer potentials calculated numerically on the lattice, we solve coupled and uncoupled systems of Schrödinger equations to obtain ...

Neural network modeling of heavy-quark potential from holography

European Physical Journal C: Particles and Fields
Using Multi-Layer Perceptrons (MLP) and Kolmogorov–Arnold Networks (KAN), we construct a holographic model based on lattice QCD data for the heavy-quark potential in the 2+1 system.
