Transverse $Λ$ polarization in $e^{+} e^{-}$ processes within a TMD factorization approach and the polarizing fragmentation function

Umberto D'Alesio, Leonard Gamberg, Francesco Murgia +1

We perform a re-analysis of Belle data for the transverse $Λ$ and $Λ ˉ$ polarization in $e^{+} e^{-}$ annihilation processes within a transverse momentum dependent (TMD) factorizatio…

New constraint on neutrino magnetic moment and neutrino millicharge from LUX-ZEPLIN dark matter search results

M. Atzori Corona, W. M. Bonivento, M. Cadeddu +2

Elastic neutrino-electron scattering represents a powerful tool to investigate key neutrino properties. In view of the recent results released by the LUX-ZEPLIN collaboration, we p…

Unpolarized Transverse Momentum Distributions from a global fit of Drell-Yan and Semi-Inclusive Deep-Inelastic Scattering data

Alessandro Bacchetta, Valerio Bertone, Chiara Bissolotti +5

We present an extraction of unpolarized transverse-momentum-dependent parton distribution and fragmentation functions based on more than two thousands data points from several expe…

Extracting the $Λ$ Polarizing Fragmentation Function from Belle $e^{+} e^{-}$ Data Within the TMD Formalism

Marco Zaccheddu, Umberto D'Alesio, Leonard Gamberg +1

Data from the Belle Collaboration for associated production (with a light unpolarized hadron) and single-inclusive production of transversely polarized $Λ$ -hyperons in $e^{+} e^{-}$ ann…

Gluon TMDs and inelastic $J / ψ$ leptoproduction at the EIC

U. D'Alesio, A. Mukherjee, F. Murgia +2

We study the Sivers azimuthal asymmetry for $J / ψ$ production in semi-inclusive deep inelastic scattering, and the still poorly known gluon Sivers function. We concentrate on the $J…

Snowmass 2021 whitepaper: Proton structure at the precision frontier

S. Amoroso, A. Apyan, N. Armesto +54

An overwhelming number of theoretical predictions for hadron colliders require parton distribution functions (PDFs), which are an important ingredient of theory infrastructure for…

General Helicity Formalism for Two-hadron Production in $e^{+} e^{-}$ Collisions and the $Λ$ Polarizing Fragmentation Function

Umberto D'Alesio, Francesco Murgia, Marco Zaccheddu

We present the complete structure of the azimuthal dependences and polarization observables for two-hadron production in $e^{+} e^{-}$ annihilation processes within a transverse momentu…
