Quantum to classical parton evolution in the QGP

João Barata, Jean-Paul Blaizot, Yacine Mehtar-Tani

We study the time evolution of the density matrix of a high energy quark in the presence of a dense QCD background that is modeled as a stochastic Gaussian color field. At late tim…

Study of a longitudinally expanding plasma with the 2PI effective action

François Gelis, Sigtryggur Hauksson

A central question in heavy-ion collisions is how the initial far-from-equilibrium medium evolves and thermalizes while it undergoes a rapid longitudinal expansion. In this work we…

decays, a serious problem for the Standard Model

Roy Aleksan, Luis Oliver

We underline the theoretical and experimental interest of the vector-vector penguin decays for which the data show a s…

Parameter optimisation using Bayesian inference for spallation models

Jason Hirtz, Jean-Christophe David, Joseph Cugnon +3

The accuracy and precision of high-energy spallation models are key issues for the design and development of new applications and experiments. We present a method to estimate model…

Sensitivity to keV-MeV dark matter from cosmic-ray scattering with current and the upcoming ground-based arrays CTA and SWGO

Igor Reis, Emmanuel Moulin, Aion Viana

A wealth of astrophysical and cosmological observational evidence shows that the matter content of the universe is made of about 85 of non-baryonic dark matter. Huge experiment…

Distinguishing models with observables

Marco Ardu, Sacha Davidson, Stéphane Lavignac

Upcoming experiments will improve the reach for the lepton flavour violating (LFV) processes , and by orders of magnitude. We investigate…

Pion PDFs confronted by Fixed-Target Charmonium Production

Wen-Chen Chang, Chia-Yu Hsieh, Yu-Shiang Lian +3

The pion, as the Goldstone boson of the strong interaction, is the lightest QCD bound state and responsible for the long-range nucleon-nucleon interaction inside the nucleus. Our k…

Parton showering with higher-logarithmic accuracy for soft emissions

Silvia Ferrario Ravasio, Keith Hamilton, Alexander Karlberg +3

The accuracy of parton-shower simulations is often a limiting factor in the interpretation of data from high-energy colliders. We present the first formulation of parton showers wi…

Potential of the Julia programming language for high energy physics computing

J. Eschle, T. Gal, M. Giordano +15

Research in high energy physics (HEP) requires huge amounts of computing and storage, putting strong constraints on the code speed and resource usage. To meet these requirements, a…

Quantum to classical parton dynamics in QCD media

João Barata, Jean-Paul Blaizot, Yacine Mehtar-Tani

We study the time evolution of the density matrix of a high energy quark propagating in a dense QCD medium where it undergoes elastic collisions (radiation is ignored in the presen…

The Two Scales of New Physics in Higgs Couplings

Raffaele Tito D'Agnolo, Florian Nortier, Gabriele Rigo +1

Higgs coupling deviations from Standard Model predictions contain information about two scales of Nature: that of new physics responsible for the deviation, and the scale where new…

Probing gluon saturation via diffractive jets in ultra-peripheral nucleus-nucleus collisions

E. Iancu, A. H. Mueller, D. N. Triantafyllopoulos +1

We argue that semi-inclusive photo-production of a pair of hard jets via coherent diffraction in nucleus-nucleus ultra-peripheral collisions at high energy is a golden channel to s…

The Invisible Dilaton

Philippe Brax, Clare Burrage, Jose A. R. Cembranos +1

We analyse the dynamics of a light scalar field responsible for the term of the Higgs potential and coupled to matter via the Higgs-portal mechanism. We find that this dilaton…

MAGO2.0: Electromagnetic Cavities as Mechanical Bars for Gravitational Waves

Asher Berlin, Diego Blas, Raffaele Tito D'Agnolo +5

Superconducting cavities can operate analogously to Weber bar detectors of gravitational waves, converting mechanical to electromagnetic energy. The significantly reduced electroma…

Exclusive meets inclusive at small Bjorken-: how to relate exclusive measurements to PDFs based on evolution equations

Hervé Dutrieux, Michael Winn, Valerio Bertone

Exclusive heavy-vector-meson photoproduction is a prominent signal in collider experiments with hadron beams. At the highest photon-hadron collision energies, this process is consi…
