Illuminating the nucleon spin
Miguel G. Echevarria
In this short note the QED extension of the nucleon spin sum rule is considered. To this end, the leading-order (LO) QED evolution kernels for the quark/gluon helicity and orbital-…
On the physics potential to study the gluon content of proton and deuteron at NICA SPD
A. Arbuzov, A. Bacchetta, M. Butenschoen +25
The Spin Physics Detector (SPD) is a future multipurpose experiment foreseen to run at the NICA collider, which is currently under construction at the Joint Institute for Nuclear R…
Quantum Simulation of Light-Front Parton Correlators
M. G. Echevarria, I. L. Egusquiza, E. Rico +1
The physics of high-energy colliders relies on the knowledge of different non-perturbative parton correlators, such as parton distribution functions, that encode the information on…
TMD factorization for dijet and heavy-meson pair in DIS
Rafael F. del Castillo, Miguel G. Echevarria, Yiannis Makris +1
We study a transverse momentum dependent (TMD) factorization framework for the processes of di-jet and heavy meson pair production in deep-inelastic-scattering in an electron-proto…
Quarkonium TMD fragmentation functions in NRQCD
Miguel G. Echevarria, Yiannis Makris, Ignazio Scimemi
We study the transverse-momentum spectrum of quarkonium production from single light-parton fragmentation mechanism. In the case of semi-inclusive deep inelastic scattering, we obs…
Studying the gluon TMDs with - and -pair production at the LHC
Florent Scarpa, Daniël Boer, Miguel G. Echevarria +3
We report on how - and -pair production are promising processes to access the polarised and unpolarised gluon TMDs at the LHC. We present the formalism used, as well as res…
