Investigating the transverse momentum dependent gluon Sivers function in quarkonium production at $pp$ colliders

U. D'Alesio, F. Murgia, C. Pisano

In this contribution, we will present a short overview of the transverse momentum dependent (TMD) approach as a tool for studying the 3-dimensional structure of hadrons in high-ene…

Constraints on light vector mediators through coherent elastic neutrino nucleus scattering data from COHERENT

M. Cadeddu, N. Cargioli, F. Dordei +4

We present new constraints on three different models, the so-called universal, $B - L$ and $L_{μ} - L_{τ}$ models, involving a yet to be observed light vector $Z^{'}$ mediator, by exploiting…

Process dependence of the gluon Sivers function in $p^{↑} p \to J / ψ + X$ within a TMD approach in NRQCD

Umberto D'Alesio, Luca Maxia, Francesco Murgia +2

We consider the transverse single-spin asymmetry (SSA) for $J / ψ$ production in $p^{↑} p \to J / ψ + X$ within a TMD approach in non-relativistic QCD. Extending a previous study […

Physics results from the first COHERENT observation of CE $ν$ NS in argon and their combination with cesium-iodide data

M. Cadeddu, F. Dordei, C. Giunti +3

We present the results on the radius of the neutron distribution in $^{40} Ar$ , on the low-energy value of the weak mixing angle, and on the electromagnetic properties of neu…

The three-dimensional distribution of quarks in momentum space

Alessandro Bacchetta, Filippo Delcarro, Cristian Pisano +1

We present the distribution of unpolarized quarks in a transversely polarized proton in three-dimensional momentum space. Our results are based on consistent extractions of the unp…

First extraction of the $Λ$ polarising fragmentation function from Belle $e^{+} e^{-}$ data

Umberto D'Alesio, Francesco Murgia, Marco Zaccheddu

We present a thorough phenomenological analysis of the experimental data from Belle Collaboration for the transverse $Λ$ and $Λ ˉ$ polarisation, measured in $e^{+} e^{-}$ annihilation…

Role of the Soffer bound in determination of transversity and the tensor charge

Umberto D'Alesio, Carlo Flore, Alexei Prokudin

The transversity and the tensor charge of the nucleon, currently under active investigation experimentally and theoretically, are fundamental quantities in hadron physics as well a…
