This report was prepared in the context of the LPCC "Electroweak Precision Measurements at the LHC WG" and summarizes the activity of a subgroup dedicated to the systematic comparison of public Monte Carlo codes, which describe the Drell-Yan processes at hadron colliders, in particular at the CERN Large Hadron Collider (LHC). This work represents an important step towards the definition of an accurate simulation framework necessary for very high-precision measurements of electroweak (EW) observables such as the $W$ boson mass and the weak mixing angle.

W gamma production in hadronic collisions using the POWHEG+MiNLO method
/ Barze, Luca (CERN) ; Chiesa, Mauro (Pavia U. ; INFN, Pavia) ; Montagna, Guido (Pavia U. ; INFN, Pavia) ; Nason, Paolo (INFN, Milan Bicocca) ; Nicrosini, Oreste (INFN, Pavia) ; Piccinini, Fulvio (INFN, Pavia) ; Prosperi, Valeria (Pavia U. ; INFN, Pavia)
We detail a calculation of W gamma production in hadronic collision, at Next-to-Leading Order (NLO) QCD interfaced to a shower generator according to the POWHEG prescription supplemented with the MiNLO procedure. The fixed order result is matched to an interleaved QCD+QED parton shower, in such a way that the contribution arising from hadron fragmentation into photons is fully modeled. [...]

Electroweak Sudakov Corrections to New Physics Searches at the LHC

We compute the one-loop electroweak Sudakov corrections to the production process $Z(\nu\bar{nu})$ + n jets, with n = 1,2,3, in p p collisions at the LHC. It represents the main irreducible background to new physics searches at the energy frontier. [...]

Neutral current Drell-Yan with combined QCD and electroweak corrections in the POWHEG BOX
/ Barze, Luca (CERN) ; Montagna, Guido (Pavia U., Dept. Fis. 'A. Volta' ; INFN, Pavia) ; Nason, Paolo (Milan Bicocca U. ; INFN, Milan Bicocca) ; Nicrosini, Oreste (INFN, Pavia) ; Piccinini, Fulvio (INFN, Pavia) ; Vicini, Alessandro (INFN, Milan ; CERN ; Milan U.)
Following recent work on the combination of electroweak and strong radiative corrections to single W-boson hadroproduction in the POWHEG BOX framework, we generalize the above treatment to cover the neutral current Drell-Yan process. According to the POWHEG method, we combine both the next-to-leading order (NLO) electroweak and QED multiple photon corrections with the native NLO and Parton Shower QCD contributions. [...]

Implementation of electroweak corrections in the POWHEG BOX: single W production
/ Barze, Luca (Pavia U. ; INFN, Pavia) ; Montagna, Guido (Pavia U. ; INFN, Pavia) ; Nason, Paolo (CERN ; INFN, Milan Bicocca ; Milan Bicocca U.) ; Nicrosini, Oreste (INFN, Pavia) ; Piccinini, Fulvio (INFN, Pavia)
We present a fully consistent implementation of electroweak and strong radiative corrections to single W hadroproduction in the POWHEG BOX framework, treating soft and collinear photon emissions on the same ground as coloured parton emissions. This framework can be easily extended to more complex electroweak processes [...]

Open questions are still present in fundamental Physics and Cosmology, like the nature of Dark Matter, the matter-antimatter asymmetry and the validity of the particle interaction Standard Model. Addressing these questions requires a new generation of massive particle detectors exploring the subatomic and astrophysical worlds. [...]
