The DNNLikelihood: enhancing likelihood distribution with Deep Learning

Andrea Coccaro, Maurizio Pierini, Luca Silvestrini +1

We introduce the DNNLikelihood, a novel framework to easily encode, through Deep Neural Networks (DNN), the full experimental information contained in complicated likelihood functi…

The partonic structure of the electron at the next-to-leading logarithmic accuracy in QED

V. Bertone, M. Cacciari, S. Frixione +1

By working in QED, we obtain the electron, positron, and photon Parton Distribution Functions (PDFs) of the unpolarised electron at the next-to-leading logarithmic accuracy. The PD…

Global Bounds on the Type-III Seesaw

Carla Biggio, Enrique Fernandez-Martinez, Manuele Filaci +2

We derive general bounds on the Type-III Seesaw parameters from a global fit to flavor and electroweak precision data. We explore and compare three Type-III Seesaw realizations: a…

Safe Use of Jet Pull

Andrew Larkoski, Simone Marzani, Chang Wu

Jet pull is an observable designed to probe colour flow between jets. Thus far, a particular projection of the pull vector, the pull angle, has been employed to distinguish colour…

A fragmentation-based study of heavy quark production

Giovanni Ridolfi, Maria Ubiali, Marco Zaro

Processes involving heavy quarks are a crucial component of the LHC physics program, both by themselves and as backgrounds for Higgs physics and new physics searches. In this work,…

Spectrum of fully-heavy tetraquarks from a diquark+antidiquark perspective

M. A. Bedolla, J. Ferretti, C. D. Roberts +1

Using a relativized diquark model Hamiltonian, we calculate the masses of $J^{P C} = 0^{++}$ ground-state tetraquarks in the following systems: $b s b ˉ s ˉ$ , $bb n ˉ n ˉ$ …

Khuri-Treiman equations for $3 π$ decays of particles with spin

JPAC Collaboration, M. Albaladejo, D. Winney +7

Khuri-Treiman equations have proven to be a useful theoretical tool in the analysis of 3-body decays, specially into the $3 π$ final state. In this work we present in full detail th…

Dalitz-plot decomposition for three-body decays

JPAC Collaboration, M. Mikhasenko, M. Albaladejo +9

We present a general formalism to write the decay amplitude for multibody reactions with explicit separation of the rotational degrees of freedom, which are well controlled by the…

Initial conditions for electron and photon structure and fragmentation functions

Stefano Frixione

In the computation of short-distance cross sections initiated by electrons and photons one can adopt the so-called structure-function approach, in which these particles play formal…

Double Polarization Observables in Pentaquark Photoproduction

JPAC Collaboration, Daniel Winney, Cristiano Fanelli +7

We investigate the properties of the hidden charm pentaquark-like resonances first observed by LHCb in 2015, by measuring the polarization transfer KLL between the incident photon…

Automated simulations beyond the Standard Model: supersymmetry

Stefano Frixione, Benjamin Fuks, Valentin Hirschi +4

The MadGraph5 aMC@NLO framework aims to automate all types of leading- and next-to-leading-order-accurate simulations for any user-defined model that stems from a renormalisable La…

$P_{c}$ pentaquarks with chiral tensor and quark dynamics

Yasuhiro Yamaguchi, Hugo Garcia-Tecocoatzi, Alessandro Giachino +4

We investigate the hidden-charm pentaquarks as superpositions of $Λ_{c} D ˉ^{(*)}$ and $Σ_{c}^{(*)} D ˉ^{(*)}$ (isospin $I = 1/2$ ) meson-baryon channels coupled to a $uudc\bar{…

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 $e^{+} e^{-}$ colliders for the thrust event shape. In this context, we perform fits of the strong coupling constant for the…

Moments of angular distribution and beam asymmetries in $η π^{0}$ photoproduction at GlueX

V. Mathieu, M. Albaladejo, C. Fernández-Ramírez +4

In the search for exotic mesons, the GlueX collaboration will soon extract moments of the $η π^{0}$ angular distribution. In the perspective of these results, we generalize the formal…

On the Equivalence of Three-Particle Scattering Formalisms

A. W. Jackura, S. M. Dawid, C. Fernández-Ramírez +5

In recent years, different on-shell $3 \to 3$ scattering formalisms have been proposed to be applied to both lattice QCD and infinite volume scattering processes. W…

Constraints on Flavor-Diagonal Non-Standard Neutrino Interactions from Borexino Phase-II

S. K. Agarwalla, M. Agostini, K. Altenmüller +103

The Borexino detector measures solar neutrino fluxes via neutrino-electron elastic scattering. Observed spectra are determined by the solar- $ν_{e}$ survival probability $P_{ee} (E)$ …
