摘要

Building upon our earlier work, we compute a Debye mass of finite-temperature Yang-Mills theory to three-loop order. As an application, we determine a g(7) contribution to the thermodynamic pressure of hot QCD.

Gravitational susceptibility of QGP

Alex Buchel

Summary: In this study, we use N = 2* and cascading gauge theory holographic models to investigate the gravitational susceptibility of strongly coupled nonconformal quark-gluon plasma. We find that in theories with a relevant coupling constant, the gravitational susceptibility depends on the renormalization scheme. To overcome this issue, we propose using the temperature derivative of the susceptibility, d kappa/dlnT, as a scheme-independent characteristic of quark-gluon plasma. Furthermore, we show that the critical behavior of kappa can vary significantly near seemingly identical thermal phase transitions.

Quarkonium semiclassical transport in quark-gluon plasma: factorization and quantum correction

Xiaojun Yao, Thomas Mehen

Summary: This study investigates quarkonium transport in a quark-gluon plasma, deriving a semiclassical Boltzmann equation and discussing the centrality and momentum dependence of the reaction rates. The research also explores ways to indirectly constrain the quarkonium in-medium real potential and quantum corrections to the semiclassical transport equation, which can be applied to understand quarkonium transport in cold nuclear matter.

1-loop matching of a thermal Lorentz force

M. Laine

Summary: The study of the diffusion and kinetic equilibration of heavy quarks within a hot QCD medium benefits from understanding the coloured Lorentz force acting on them. By determining 1-loop matching coefficients for the electric and magnetic parts of a Lorentz force, it enables a lattice study of a color-magnetic 2-point correlator.

Broad excitations in a 2+1D overoccupied gluon plasma

K. Boguslavski, A. Kurkela, T. Lappi, J. Peuron

Summary: This research focuses on the excitations of far-from-equilibrium 2+1 dimensional gauge theories and finds that their structure is nontrivial and nonperturbative, leading to broad excitation peaks in spectral and statistical correlation functions. The absence of soft quasiparticles in these theories is demonstrated by the comparable width of these peaks to the frequency of soft excitations.

Non-perturbative thermal QCD at all temperatures: the case of mesonic screening masses

Mattia Dalla Brida, Leonardo Giusti, Tim Harris, Davide Laudicina, Michele Pepe

Summary: This study presents a strategy based on the step-scaling technique to nonperturbatively study thermal QCD up to very high temperatures, specifically focusing on computing flavour non-singlet meson screening masses in a theory with three massless quarks. Chiral symmetry restoration is observed in the results, with deviations in meson screening masses not explained by the known leading term in the QCD coupling constant g. The research findings provide insight into the difficulties in matching non-perturbative lattice results at lower temperatures with the behavior at asymptotically high temperatures.

Holographic drag force in non-conformal plasma

Tolga Domurcukgul, Razieh Morad

Summary: In this study, the dynamics of a moving heavy quark in a strongly coupled, non-conformal plasma were investigated using the gauge/string duality. It was found that the drag force in this non-conformal model is smaller and decreases as the level of non-conformality increases.

Spin relaxation rate for heavy quarks in weakly coupled QCD plasma

Masaru Hongo, Xu-Guang Huang, Matthias Kaminski, Mikhail Stephanov, Ho-Ung Yee

Summary: We calculate the relaxation rate of the spin density of heavy quarks in a perturbative QCD plasma and demonstrate the differences between three different methods of calculation, while finding that the relaxation rate of the spin is smaller than that of other non-hydrodynamic modes in the heavy-quark limit.

Deep inelastic scattering on the quark-gluon plasma

Marco Ce, Tim Harris, Harvey B. Meyer, Arianna Toniato

Summary: The article interprets the structure functions of a thermal medium in terms of electron scattering and exchange of spacelike photons, focusing on deep-inelastic scattering and moment sum rules obeyed by the structure functions. It discusses the thermal expectation value of twist-two operators computable in lattice QCD, as well as how lattice QCD calculations can probe the virtuality required for Bjorken scaling. Moreover, it provides a parton-model interpretation of structure functions in the Bjorken limit and tests its consistency.

Second order chiral kinetic theory under gravity and antiparallel charge-energy flow

Tomoya Hayata, Yoshimasa Hidaka, Kazuya Mameda

Summary: In this study, we derived the chiral kinetic theory under the presence of gravitational Riemann curvature and discovered new types of fermionic transport phenomena, including charge current and energy-momentum tensor induced by the curvature. It was found that inhomogeneous fluid vorticity can induce charge and energy currents in opposite directions, due to the spin-curvature coupling. Additionally, possible applications to Weyl/Dirac semimetals and heavy-ion collision experiments were briefly discussed.

Spin polarization induced by the hydrodynamic gradients

Shuai Y. F. Liu, Yi Yin

Summary: The study systematically analyzes the effects of derivatives of hydrodynamic fields on the axial Wigner function describing spin polarization vector in phase space. By considering all possible first-order derivative contributions allowed by symmetry and using linear response theory, the study identifies potentially significant contributions, especially the quadrupole induction for spin polarization due to shear strength. The results, together with hydrodynamic gradients from simulations, provide a basis for interpreting spin polarization measurements in heavy-ion collisions.

Off-equilibrium non-Gaussian fluctuations near the QCD critical point: an effective field theory perspective

Noriyuki Sogabe, Yi Yin

Summary: This paper uses the effective field theory of fluctuating hydrodynamics to study the real-time critical non-Gaussian fluctuations of a conserved charge density. The study finds that non-linear interactions among noise fields could potentially contribute to the quartic fluctuations in the scaling regime even at tree level in off-equilibrium situations.

Effective Field Theory for jet substructure in heavy ion collisions

Varun Vaidya

Summary: The author developed an Effective Field Theory (EFT) framework to compute jet substructure observables for heavy ion collision experiments, focusing on a dijet system accompanying the formation of a weakly coupled long lived Quark Gluon Plasma (QGP) medium. By treating the jet as an open quantum system, the author derived a factorization formula within the SCET framework to study the evolution and interaction of the jet within the medium. This factorization formula led to a Lindblad type equation for the reduced density matrix of the jet, allowing a resummation of large logarithms and summing over multiple incoherent interactions with the medium.

Phenomenology of strong interactions: towards an effective theory for low energy QCD

Adamu Issifu, Francisco A. A. Brito

Summary: This paper develops models for phenomenological particle physics based on the string analogy of particles. These models can be used to investigate various phenomenological aspects, including confinement, deconfinement, chiral condensate, QGP phase transitions, and the evolution of the early universe. Additionally, properties such as scalar glueball mass, gluon mass, glueball-meson mixing states, QCD vacuum, and color superconductivity can also be explored using these model frameworks. The paper concludes by using one of the models to describe the phenomenon of color confinement among glueballs. These models are built upon the modified Dirac-Born-Infeld (DBI) action for open strings with endpoints on a Dp-brane or brane-anti-brane at a tachyonic vacuum.
