HERA data and collinearly-improved BK dynamics

B. Ducloué, E. Iancu, G. Soyez +1

Within the framework of the dipole factorisation, we use a recent collinearly-improved version of the Balitsky-Kovchegov equation to fit the HERA data for inclusive deep inelastic…

Learning Multivariate New Physics

Raffaele Tito D'Agnolo, Gaia Grosso, Maurizio Pierini +2

We discuss a method that employs a multilayer perceptron to detect deviations from a reference model in large multivariate datasets. Our data analysis strategy does not rely on any…

Multi-Quark Colour Decompositions from Unitarity

Alexander Ochirov, Ben Page

Any loop QCD amplitude at full colour is constructed from kinematic and gauge-group building blocks. In a unitarity-based on-shell framework, both objects can be reconstructed from…

V and heavy flavour production: status and recent theoretical developments

Davide Napoletano

In this talk, we review the status of the associated production of a vector boson and heavy flavour quarks, and some recent theoretical developments. While some aspects of these mu…

The single-jet inclusive cross-section and its definition

Matteo Cacciari, Stefano Forte, Davide Napoletano +2

We investigate some well-known problematic aspects of the single-jet inclusive cross-section, specifically its non-unitarity and the possibly related issue of apparent perturbative…

Fitting the Strong Coupling Constant with Soft-Drop Thrust

Simone Marzani, Daniel Reichelt, Steffen Schumann +2

Soft drop has been shown to reduce hadronisation effects at colliders for the thrust event shape. In this context, we perform fits of the strong coupling constant for the…

Orbital angular momentum of the proton and intrinsic five-quark Fock states

C. S. An, B. Saghai

The orbital angular momentum () of the proton is studied by employing the extended constituent quark model. Contributions from different flavors, namely, up, down, strange, an…

Analytic Form of the Planar Two-Loop Five-Parton Scattering Amplitudes in QCD

S. Abreu, J. Dormans, F. Febres Cordero +3

We present the analytic form of all leading-color two-loop five-parton helicity amplitudes in QCD. The results are analytically reconstructed from exact numerical evaluations over…

Fitting the b-quark PDF as a massive-b scheme: Higgs production in bottom fusion

Stefano Forte, Tommaso Giani, Davide Napoletano

We show that a simple and accurate approach to the computation of hadron collider processes involving initial-state quarks can be obtained by introducing an independently param…

Unbiased determination of DVCS Compton Form Factors

H. Moutarde, P. Sznajder, J. Wagner

The extraction of Compton Form Factors (CFFs) in a global analysis of almost all Deeply Virtual Compton Scattering (DVCS) proton data is presented. The extracted quantities are DVC…

Physics potential of the International Axion Observatory (IAXO)

E. Armengaud, D. Attie, S. Basso +88

We review the physics potential of a next generation search for solar axions: the International Axion Observatory (IAXO). Endowed with a sensitivity to discover axion-like particle…

Angular mode expansion of the Boltzmann equation in the small-angle approximation

Jean-Paul Blaizot, Naoto Tanji

We use an expansion in angular mode functions in order to solve the Boltzmann equation for a gluon plasma undergoing longitudinal expansion. By comparing with the exact solution ob…

Gauge ambiguity of the quark spectrum in the Color Glass Condensate

Francois Gelis, Naoto Tanji

In the Color Glass Condensate, the inclusive spectrum of produced quarks in a heavy ion collision is obtained as the Fourier transform of a -fermion correlation function. Due to…

Acoustic Rabi oscillations between gravitational quantum states and impact on symmetron dark energy

Gunther Cronenberg, Philippe Brax, Hanno Filter +6

The standard model of cosmology provides a robust description of the evolution of the universe. Nevertheless, the small magnitude of the vacuum energy is troubling from a theoretic…
