Global analysis of fragmentation functions to charged hadrons with high-precision data from the LHC
[arXiv:2407.04422]
Fragmentation functions (FFs) are essential nonperturbative QCD inputs for predicting hadron production cross sections in high energy scatterings. In this study, we present a joint determination of FFs for light charged hadrons through a global analysis at next-to-leading order (NLO) in QCD. [...]

CaloChallenge 2022: A Community Challenge for Fast Calorimeter Simulation
[FERMILAB-PUB-24-0728-CMS; HEPHY-ML-24-05; TTK-24-43; arXiv:2410.21611]
 GO
We present the results of the 'Fast Calorimeter Simulation Challenge 2022' - the CaloChallenge. We study state-of-the-art generative models on four calorimeter shower datasets of increasing dimensionality, ranging from a few hundred voxels to a few tens of thousand voxels. [...]

Particle Loss by Touschek Effect in a Storage Ring
[DESY-67-005]
A formula for the loss rate of electrons from a stored beam due to the so-called "Touschek Effect" is derived starting with the exact M~ller scattering crosssection. For rectangular distribution of transverse momentum, this formula is integrated explicitly. [...]

Higgs-muon interactions at a multi-TeV muon collider
[COMETA-2024-25; DESY-24-150; IRMP-CP3-24-29; MSUHEP-24-017; PITT-PACC-2410; SI-HEP-2024-22; arXiv:2410.06991]
We establish a simple yet general parameterization of Higgs-muon interactions within the effective field theory frameworks, including both the Higgs Effective Field Theory (HEFT) and the Standard Model Effective Field Theory (SMEFT). We investigate the potential of a muon collider, operating at center-of-mass energies of 3 and 10 TeV, to probe Higgs-muon interactions. [...]

Towards a vacuum birefringence experiment at the Helmholtz International Beamline for Extreme Fields (Letter of Intent of the BIREF@HIBEF Collaboration)
[arXiv:2405.18063]
Quantum field theory predicts a nonlinear response of the vacuum to strong electromagnetic fields of macroscopic extent. This fundamental tenet has remained experimentally challenging and is yet to be tested in the laboratory. [...]

Variational quantum eigensolver for causal loop Feynman diagrams and directed acyclic graphs
[IFIC/22-28; arXiv:2210.13240]
We present a variational quantum eigensolver (VQE) algorithm for the efficient bootstrapping of the causal representation of multiloop Feynman diagrams in the loop-tree duality or, equivalently, the selection of acyclic configurations in directed graphs. A loop Hamiltonian based on the adjacency matrix describing a multiloop topology, and whose different energy levels correspond to the number of cycles, is minimized by VQE to identify the causal or acyclic configurations.

Detecting and mitigating mode-collapse for flow-based sampling of lattice field theories
[arXiv:2302.14082]
We study the consequences of mode-collapse of normalizing flows in the context of lattice field theory. Normalizing flows allow for independent sampling. [...]

Nonperturbative renormalization of asymmetric staple-shaped operators in twisted mass lattice QCD
[arXiv:2305.11824]
Staple-shaped Wilson line operators are necessary for the study of transverse momentum-dependent parton distribution functions (TMDPDFs) in lattice QCD and beyond. In this work, we study the renormalization of such operators in the general case of an asymmetric staple. [...]

Measurements of the inclusive W and Z boson production cross sections and their ratios in proton-proton collisions at $\sqrt{s}$ = 13.6 TeV
[CERN-EP-2025-013; CMS-SMP-22-017; arXiv:2503.09742]
Measurements are presented of the W and Z boson production cross sections in proton-proton collisions at a center-of-mass energy of 13.6 TeV. Data collected in 2022 and corresponding to an integrated luminosity of 5.01 fb$^{-1}$ with one or two identified muons in the final state are analyzed. [...]

Small-$x$ evolution of gluon fields from incoherent J/$\psi$ photoproduction in ultraperipheral PbPb collisions
[CERN-EP-2025-030; CMS-HIN-23-009; arXiv:2503.08903]
Incoherent J/$\psi$ photoproduction in heavy ion ultraperipheral collisions (UPCs), in which the photon interacts with localized, fluctuating gluonic hotspots rather than the entire nucleus, provides a unique probe of those fluctuations. This study presents the first measurement of the dependence of this photoproduction yield on the photon-nucleon center-of-mass energy ($W_\gamma^\mathrm{N}$), using PbPb UPCs at a nucleon-nucleon center-of-mass energy of 5.02 TeV.
