The discovery by the ATLAS and CMS experiments of a new boson with mass around 125 GeV measured properties compatible those Standard-Model Higgs boson, coupled absence discoveries phenomena beyond Standard Model at TeV scale, has triggered interest in ideas for future factories. A circular e+e- collider hosted 80 to 100 km tunnel, TLEP, is among most attractive solutions proposed so far. It clean experimental environment, produces high luminosity top-quark, W Z studies, accommodates multiple...
The discovery of the Higgs boson in 2012, by ATLAS and CMS experiments, was a success achieved with only percent entire dataset foreseen for LHC. It opened landscape possibilities study properties, Electroweak Symmetry breaking Standard Model general, as well new avenues probing physics beyond Model. Six years after discovery, conspicuously larger collected during LHC Run 2 at 13 TeV centre-of-mass energy, theory experimental particle communities have started meticulous exploration potential...

We propose a new experiment to measure the running of electromagnetic coupling constant in space-like region by scattering high-energy muons on atomic electrons low-Z target through elastic process $$\mu \, e \rightarrow \mu e$$ . The differential cross section this process, measured as function squared momentum transfer $$t=q^2<0$$ , provides direct sensitivity leading-order hadronic contribution muon anomaly $$a^\mathrm{{HLO}}_{\mu }$$ By using beam 150 GeV, with an average rate $$\sim $$...

A bstract We present a fully consistent implementation of electroweak and strong radiative corrections to single W hadroproduction in the POWHEG BOX framework, treating soft collinear photon emissions on same ground as coloured parton emissions. This framework can be easily extended more complex processes. describe how next-to-leading order (NLO) are combined with NLO QCD calculation, show they interfaced QED shower Monte Carlo. The resulting tool fills gap literature allows study...
In view of precision studies the Higgs sector at Run II LHC, improvement accuracy theoretical prediction is becoming a pressing issue. this framework, we detail calculation full Next-to-Leading Order (NLO) electroweak corrections to boson decay into four charged leptons, by considering gold-plated channel H → Z (∗) 2ℓ2ℓ ′ , ℓ, ℓ = e, μ. We match NLO with QED Parton Shower (PS), in order simulate exclusive multiple photon emission and provide novel results NLOPS accuracy. compare our...
We perform a comprehensive analysis of electroweak, QED and mixed QCD-electroweak corrections underlying the precise measurement W-boson mass M_W at hadron colliders. By applying template fitting technique, we detail impact on next-to-leading order electroweak QCD corrections, multiple photon emission, lepton pair radiation factorizable contributions. As by-product, provide an up-to-date estimate main theoretical uncertainties perturbative nature. Our results can serve as guideline for...

Several key observables of the high-precision physics program at future lepton colliders will critically depend on knowledge absolute machine luminosity. The determination luminosity relies precise some reference process, which is in principle not affected by unknown physics, so that its cross section can be computed within a well-established theory, like Standard Model. Quantifying uncertainties induced possible New Physics effects such processes therefore crucial. We present an exploratory...
The impact of higher-order final-state photonic corrections on the precise determination W-boson mass at Tevatron and LHC colliders is evaluated. In presence realistic selection criteria, shift in W from a fit to transverse distribution found be about 10 MeV $W \to \mu \nu$ channel almost negligible e channel. calculation, which implemented Monte Carlo event generator for data analysis, can contribute reduce uncertainty associated measurement future hadron collider experiments.

On one hand, we performed a variety experimental theoretical studies on standard candles (such as W, Z, ttbar production), treating them either proper signals known physics, or backgrounds to unknown physics; also addressed issues relevant those non-perturbative semi-perturbative ingredients, such Parton Density Functions Underlying Events, whose...
