Open AccessQuark production and thermalization of the quark-gluon plasma
We first assemble a full set of the Boltzmann Equation in Diffusion Approximation (BEDA) for studying thermalization/hydrodynamization as well as the production of massless quarks and antiquarks in out of equi...

In this work, we analyze the strong vertices \(\Sigma _{c}\Delta D^{*}\) ...

Open AccessAnisotropic flow and the valence quark skeleton of hadrons
We study transverse momentum anisotropies, in particular, the elliptic flow v2 due to the interference effect sourced by valence quarks in high-energy hadron-hadron collisions. Our main formula is derived as the ...

Open AccessPrecision boson-jet azimuthal decorrelation at hadron colliders
The azimuthal angular decorrelation of a vector boson and jet is sensitive to QCD radiation, and can be used to probe the quark-gluon plasma in heavy-ion collisions. By using a recoil-free jet definition, the ...

Open AccessRuppeiner geometry and thermodynamic phase transition of the black hole in massive gravity
The phase transition and thermodynamic geometry of a 4-dimensional AdS topological charged black hole in de Rham, Gabadadze and Tolley (dRGT) massive gravity have been studied. After introducing a normalized t...

Open AccessFactorization and transverse phase-space parton distributions
We first revisit impact-parameter dependent collisions of ultra-relativistic particles in quantum field theory. Two conditions sufficient for defining an impact-parameter dependent cross section are given, whi...

Open AccessDiagnosis inspired by the thermodynamic geometry for different thermodynamic schemes of the charged BTZ black hole
Due to the asymptotic structure of the black hole solution, there are two different thermodynamic schemes for the charged Banados–Teitelboim–Zanelli (BTZ) black hole. In one scheme, the charged BTZ black hole ...

Open AccessFlow in AA and pA as an interplay of fluid-like and non-fluid like excitations
To study the microscopic structure of quark–gluon plasma, data from hadronic collisions must be confronted with models that go beyond fluid dynamics. Here, we study a simple kinetic theory model that encompass...

Open AccessResummation of boson-jet correlation at hadron colliders
We perform a precise calculation of the transverse momentum ( q ...

Open AccessOpacity dependence of elliptic flow in kinetic theory
The observation of large azimuthal anisotropies \(v_n\)vn in the particle spectra of proton–proton (pp) and proton–nucleus (pA) collisions challenges fluid dynamic interpretations of \(v_n\)vn, as it remains uncl...

Open AccessTime-dependent observables in heavy ion collisions. Part I. Setting up the formalism
We adapt the Schwinger-Keldysh formalism to study heavy-ion collisions in perturbative QCD. Employing the formalism, we calculate the two-point gluon correlation function G 22 ...

Open AccessTime-dependent observables in heavy ion collisions. Part II. In search of pressure isotropization in the φ4 theory
To understand the dynamics of thermalization in heavy ion collisions in the perturbative framework it is essential to first find corrections to the free-streaming classical gluon fields of the McLerran-Venugop...

Open AccessThermalization of mini-jets in a quark-gluon plasma
We complete the physical picture for the evolution of a high-energy jet propagating through a weakly-coupled quark-gluon plasma by investigating the thermalization of the soft components of the jet. We argue t...

Open AccessKinetic theory of a longitudinally expanding system of scalar particles
A simple kinematical argument suggests that the classical approximation may be inadequate to describe the evolution of a system with an anisotropic particle distribution. In order to verify this quantitatively...

Open AccessLattice worldline representation of correlators in a background field
We use a discrete worldline representation in order to study the continuum limit of the one-loop expectation value of dimension two and four local operators in a background field. We illustrate this technique ...

Open AccessFlat space compressible fluid as holographic dual of black hole with curved horizon
We consider the fluid dual of (d + 2)-dimensional vacuum Einstein equation either with or without a cosmological constant. The background solutions admit black hole event horizons and the spatial sections of the ...

Open AccessRadiative energy loss and radiative p ⊥-broadening of high-energy partons in QCD matter
We study the connection between radiative energy loss and radiative p ⊥- roadening of a high-energy quark or gluon passing through QCD matter. The generalized Baier-Dokshitzer-Mueller-Peig...

Open AccessOn holographic thermalization and gravitational collapse of tachyonic scalar fields
In this paper we study the thermalization of a spatially homogeneous system in a strongly coupled CFT. The non-equilibrium initial state is created by switching on a relevant perturbation in the CFT vacuum dur...

On using cold baryogenesis to constrain the two-Higgs doublet model
We consider the creation of the cosmological baryon asymmetry in the Two Higgs Doublet Model. We imagine a situation where the masses of the five Higgs particles and the two Higgs vevs are constrained by colli...
