Artificial neural network modelling of generalised parton distributions

H. Dutrieux, O. Grocholski, H. Moutarde +1

We discuss the use of machine learning techniques in effectively nonparametric modelling of generalised parton distributions (GPDs) in view of their future extraction from experime…

Quarks and gluons in the Lund plane

Frederic Dreyer, Gregory Soyez, Adam Takacs

Discriminating quark and gluon jets is a long-standing topic in collider phenomenology. In this paper, we address this question using the Lund jet plane substructure technique intr…

Co-interacting dark matter and conformally coupled light scalars

Philippe Brax, Carsten van de Bruck, Sebastian Trojanowski

The increasing observational pressure on the standard cosmological model motivates analyses going beyond the paradigm of the collision-less cold dark matter (DM). Since the only cl…

Phenomenology of jet angularities at the LHC

Daniel Reichelt, Simone Caletti, Oleh Fedkevych +3

We compute resummed and matched predictions for jet angularities in hadronic dijet and Z+jet events with and without grooming the candidate jets using the SoftDrop technique. Our t…

Probing parton saturation and the gluon dipole via diffractive jet production at the Electron-Ion Collider

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

We demonstrate that hard dijet production via coherent inelastic diffraction is a promising channel for probing gluon saturation at the Electron-Ion Collider. By $in e l a s t i c$ diffra…

Dynamically groomed jet radius in heavy-ion collisions

Paul Caucal, Alba Soto-Ontoso, Adam Takacs

We explore the ability of a recently proposed jet substructure technique, Dynamical Grooming, to pin down the properties of the Quark-Gluon Plasma formed in ultra-relativistic heav…

Status and Perspectives of Neutrino Physics

M. Sajjad Athar, Steven W. Barwick, Thomas Brunner +16

This review demonstrates the unique role of the neutrino by discussing in detail the physics of and with neutrinos. We deal with neutrino sources, neutrino oscillations, absolute m…

Nonunitarity of the lepton mixing matrix at the European Spallation Source

Sabya Sachi Chatterjee, O. G. Miranda, M. Tórtola +1

If neutrinos get mass through the exchange of lepton mediators, as in seesaw schemes, the neutrino appearance probabilities in oscillation experiments are modified due to effective…

Building a realistic neutron star from holography

Nicolas Kovensky, Aaron Poole, Andreas Schmitt

We employ the recently improved description of dense baryonic matter within the Witten-Sakai-Sugimoto model to construct neutron stars. In contrast to previous holographic approach…

High $P_{T}$ Higgs excess as a signal of non-local QFT at the LHC

Xing-Fu Su, You-Ying Li, Rosy Nicolaidou +3

Non-local extensions of the Standard Model with a non-locality scale $Λ_{N L}$ have the effect of smearing the pointlike vertices of the Standard Model. At energies significantly lo…

Deeply virtual Compton scattering off the neutron

M. Benali, C. Desnault, M. Mazouz +96

The three-dimensional structure of nucleons (protons and neutrons) is embedded in so-called generalized parton distributions, which are accessible from deeply virtual Compton scatt…

Sliding Naturalness: Cosmological Selection of the Weak Scale

Raffaele Tito D'Agnolo, Daniele Teresi

We present a cosmological solution to the electroweak hierarchy problem. After discussing general features of cosmological approaches to naturalness, we extend the Standard Model w…

CP violation and determination of the $b s$ "flat" unitarity triangle at FCCee

Roy Aleksan, L. Oliver, Emmanuel Perez

We investigate the sensitivity with which two angles of the "flat" unitarity triangle, defined by $V_{u b}^{*} V_{u s} + V_{c b}^{*} V_{cs} + V_{t b}^{*} V_{t s} = 0$ , can possibly be measured…

Phenomenological study of quarkonium suppression and the impact of the energy gap between singlets and octets

Jean-Paul Blaizot, Miguel Ángel Escobedo

The study of heavy quarkonium suppression in heavy-ion collisions represents an important source of information about the properties of the quark-gluon plasma produced in such coll…

Stellar Shocks From Dark Matter Asteroid Impacts

Anirban Das, Sebastian A. R. Ellis, Philip C. Schuster +1

Macroscopic dark matter is almost unconstrained over a wide "asteroid-like" mass range, where it could scatter on baryonic matter with geometric cross section. We show that when su…

Medium-induced radiative kernel with the Improved Opacity Expansion

João Barata, Yacine Mehtar-Tani, Alba Soto-Ontoso +1

We calculate the fully differential medium-induced radiative spectrum at next-to-leading order (NLO) accuracy within the Improved Opacity Expansion (IOE) framework. This scheme all…
