Thanks to the large amount of data that is being and will be collected at Run-III and High Luminosity (HL) stage, precision measurements at the LHC are reaching an unprecedented level of statistical accuracy, whilst PDF uncertainties prevail. We study the impact of future measurements of lepton-charge and forward-backward asymmetries on PDF determination. The numerical results have been...
Drell-Yan lepton pair production is a benchmark process at hadron colliders.
From the theoretical side, the inclusion of higher-order radiative corrections is mandatory
in order to match the experimental accuracy attainable at the LHC.
QCD radiative corrections are known up to order $\alpha^3_s$ for inclusive cross
sections and up to order $\alpha^2_s$ for differential observables; EW...
The target precision for $W$-mass measurements at the LHC is around 0.1 permille, an extremely ambitious goal that requires exceptional theoretical control on vector boson production. I will present the results of a recent calculation of the mixed QCD $\times$ EW corrections to $W$ and $Z$ boson production. I will then discuss the impact of these corrections on the measurement of the $W$ boson...
We present the results of the recent study published in Phys.Rev.Lett. 126 (2021) 4, 041801, where the PDF uncertainty affecting the MW determination at the LHC is estimated keeping into account the full correlations information from the PDF at the level of the differential distribution used to extract $M_W$, namely $p_T^l$.
We find that keeping these correlations into account can reduce...
