The Spin Physics Detector, a universal facility for studying the nucleon spin structure and other spin-related phenomena with polarized proton deuteron beams, is proposed to be placed in one of two interaction points NICA collider that under construction at Joint Institute Nuclear Research (Dubna, Russia). At heart project there huge experience beams JINR. main objective experiment comprehensive study unpolarized gluon content nucleon. measurements Detector have bright perspectives make...
The Spin Physics Detector collaboration proposes to install a universal detector in the second interaction point of NICA collider under construction (JINR, Dubna) study spin structure proton and deuteron other spin-related phenomena using unique possibility operate with polarized beams at collision energy up 27 GeV luminosity $10^{32}$ cm$^{-2}$ s$^{-1}$. As main goal, experiment aims provide access gluon TMD PDFs deuteron, as well transversity distribution tensor via measurement specific...
Numerical simulations of three and four top quark hadroproduction processes are carried out in the SMEFT model framework. The simulated data used to derive expected theoretical constraints on Wilson coefficients relevant operators dimension six. Obtained limits for both cases discussed compared terms processes’ sensitivity possible BSM contribution. Results show that operator [Formula: see text] is better constrained by process production, whereas other text], similarly production processes....
Numerical simulations of processes three and four top quark hadroproduction are carried out in the SMEFT model framework. The simulated data used to derive expected theoretical constraints on Wilson coefficients relevant operators dimension six. Obtained limits for both cases discussed compared terms sensitivity possible BSM contribution. Results show that operator $O_{tt}^1$ is better constrained by process production, whereas other $O_{QQ}^1$, $O_{Qt}^1$, $O_{Qt}^8$ $O_{QQ}^8$, similarly...
The new method for studying polarized parton distribution functions via the Drell-Yan process with tau production is proposed. hadronic decay of to single charged pi-meson and neutrino utilised determination polarization state tau-lepton. key feature our approach that we do not sum over polarizations states tau, but preserve this information through energies ofpions produced in corresponding decays. addition existing ones should improve accuracy measurements structure hadrons. In current...
