Cylindrically Symmetric Diffusion Model for Relativistic Heavy‐Ion Collisions

Annalen der Physik, Volume 536, Issue 5, May 2024.
To account for particle production in relativistic heavy‐ion collisions at the Large Hadron Collider, a relativistic diffusion model with cylindrical symmetry is derived from nonequilibrium–statistical considerations. It propagates an initial state based on quantum chromodynamics in time toward a thermal equilibrium limit.

Non-relativistic quantum chromodynamics in parton showers

European Physical Journal C: Particles and Fields
Measurements of quarkonia isolation in jets at the Large Hadron Collider (LHC) have been shown to disagree with fixed-order non-relativistic quantum chromodynamics (NRQCD) calculations, even at higher orders.

Two-loop HTL pressure at finite temperature and chemical potential

, 2013
We calculate the two-loop pressure of a plasma of quarks and gluons at finite temperature and chemical potential using the hard thermal loop perturbation theory (HTLpt) reorganization of finite temperature/density quantum chromodynamics.

Pion loops in quenched Quantum Chromodynamics [PDF]

, 1997
We calculate the divergences of the generating functional of quenched Chiral Perturbation Theory to one loop for a generic number of flavours. The flavour number dependence of our result enlightens the mechanism of quark loop cancellation in the quenched

Limits on Dark Photons, Scalars, and Axion‐Electromagnetodynamics with the ORGAN Experiment

Annalen der Physik, Volume 536, Issue 1, January 2024.
The nature of dark matter is one of the biggest mysteries in the Universe. ORGAN is an experiment which seeks to understand dark matter by figuring out what it is made of. In this article, the current sensitivity of ORGAN to various promising dark matter candidates is presented, and the future sensitivity is projected.

Running of the top quark mass at NNLO in QCD

Journal of High Energy Physics
The running of the top quark mass (m t) is probed at the next-to-next-to-leading order in quantum chromodynamics for the first time. The result is obtained by comparing calculations in the modified minimal subtraction ( $$\overline{{\text{MS ...
