Introduction to transverse momentum imaging
Andrea Signori
This set of notes complements the lectures and recitation sessions discussed in the following graduate schools: HUGS at Jefferson Lab (years 2018, 2019, 2021), the International Sc…
Toward universal coalescence models for antideuteron production
Mattia di Mauro, Jordan Koechler, Lorenzo Stefanuto +3
Cosmic-ray (CR) antinuclei, especially antideuteron and antihelium-3 nuclei , are among the most promising messengers for indirect dark ma…
Axions at the meV Crossroads: Theory, Cosmology, Astrophysics, and Experiments
Michele Cicoli, Francesco D'Eramo, Luca Di Luzio +18
The meV mass range has emerged as a focal point in axion physics, where advances in theory, cosmology, astrophysics, and experimental techniques converge. Axions in this mass range…
Additional results on the four-loop flavour-singlet splitting functions in QCD
G. Falcioni, F. Herzog, S. Moch +2
We have extended our previous computations, performed analytically for a general gauge group, of the even- moments of the four-loop flavour-singlet split…
Quantum entanglement between partons in a strongly coupled quantum field theory
Wenyu Zhang, Wenyang Qian, Yiyu Zhou +2
We perform a first-principles, non-perturbative investigation of quantum entanglement between partonic constituents in a strongly coupled 3+1-dimensional scalar Yukawa theory, usin…
Disperon QED
Yizhou Fang, Sophie Kollatzsch, Marco Rocco +3
We present disperon QED, a method to deal with data input in loop processes in Monte Carlo codes. It relies on dispersion relations, automated tools such as OpenLoops, effective fi…
Two-loop all-plus helicity amplitudes for self-dual Higgs boson with gluons via unitarity cut constraints
Simon Badger, Christian Biello, Colomba Brancaccio +1
We present the two-loop amplitudes for a self-dual Higgs boson with up to four positive helicity gluons in the heavy top-quark limit. Because the tree amplitudes in the all-plus se…
Stellar-like Galactic center excess challenges particle dark matter
Silvia Manconi, Christopher Eckner, Francesca Calore +1
The Galactic Center (GC) is potentially hosting the largest indirect signal from particle dark matter (DM), which in many well-motivated models would produce gamma rays as their fi…
INTEGRAL, eROSITA and Voyager Constraints on Light Bosonic Dark Matter: ALPs, Dark Photons, Scalars, and Vectors
Thong T. Q. Nguyen, Pedro De la Torre Luque, Isabelle John +3
The decay of light bosonic dark matter particles can produce a bright electron/positron () flux that can be strongly constrained by local Voyager observations of the direct…
Numerical computation of Fox functions
Giampiero Passarino
In this work we discuss techniques for the numerical computation of Fox functions that represent Feynman integrals. Illustrative examples based on Sinc numerical methods and Quasi-…
Feynman Fox integrals in the physical region
Giampiero Passarino
Feynman integrals in the physical region are transformed into Fox functions with a special emphasys to their cut structure
One-loop amplitudes for and productions at the LHC through
Souvik Bera, Colomba Brancaccio, Dhimiter Canko +1
We present analytic expressions for the one-loop QCD helicity amplitudes contributing to top-quark pair production in association with a photon or a jet at the Large Hadron Collide…
Antinuclei from Primordial Black Holes
Valentina De Romeri, Fiorenza Donato, David Maurin +2
Light primordial black holes (PBHs) may have originated in the early Universe, and could contribute to the dark matter in the Universe. Their Hawking evaporation into particles cou…
The two-loop Higgs impact factor
Vittorio Del Duca, Giulio Falcioni
In the HEFT, we consider the Regge limit of the two-loop amplitudes for Higgs boson production in association with a jet, expanded to NNLL accuracy. We discuss the issue of the Reg…

We investigate the properties of charmonium systems in strong external magnetic fields using a relativistic light-front Hamiltonian approach within the Basis Light-Front Quantizati…
Big Bang Nucleosynthesis as a probe of non-standard neutrino interactions and non-unitary three-neutrino mixing
Gabriela Barenboim, Stefano Gariazzo, Alberto Sánchez-Vargas
In this work we investigate the impact of two phenomenological Beyond the Standard Model (BSM) scenarios concerning the role of neutrinos in the early universe: non-standard neutri…
Global analysis of fragmentation functions to light neutral hadrons
Jun Gao, ChongYang Liu, Mengyang Li +4
Fragmentation functions (FFs) are crucial non-perturbative components in quantum chromodynamics (QCD), playing a vital role in predictions and understanding of the hadronization pr…
Regge poles and cuts and the Lipatov vertex
Samuel Abreu, Giulio Falcioni, Einan Gardi +2
Scattering amplitudes in the high-energy limit can be described in terms of their singularity structure in the complex angular momentum plane, consisting of Regge poles and cuts. I…
