The current status of the theoretical precision for Bhabha luminometry is critically reviewed and pathways are outlined to requirement targeted by FCC-ee studies. Various components pertinent error budget discussed in detail – starting from context LEP experiments, through their updates, up prospects improvements sake FCC-ee. It argued that, with an appropriate upgrade Monte Carlo event generator BHLUMI and/or other similar MC programs calculating QED effects low angle process, total 0.01%...
This report summarises the results of four-fermion working group LEP2-MC workshop, held at CERN from 1999 to 2000. Recent developments in calculation processes electron-positron collisions LEP-2 centre-of-mass energies are presented, concentrating on predictions for four main reactions: W-pair production, visible photons events, single-W production and Z-pair production. Based a comparison derived within different approaches, theoretical uncertainties these established.
We present the results obtained by "WW Cross-sections and Distributions" working group during CERN Workshop "Physics at LEP2" (1994/1995)
We present the theoretical basis and sample Monte Carlo data for YFS exponentiated calculation of ${e}^{+}{e}^{\ensuremath{-}}\ensuremath{\rightarrow}{W}^{+}{W}^{\ensuremath{-}}\ensuremath{\rightarrow}{f}_{1}{\overline{f}}_{1}^{\ensuremath{'}}+{\overline{f}}_{2}{f}_{2}^{\ensuremath{'}}$ at beyond CERN LEP 2 energies, where left-handed parts ${f}_{i}$ ${f}_{i}^{\ensuremath{'}}$ are respective upper lower components an $\mathrm{SU}{(2)}_{L}$ doublet, $i=1, 2$.

A methodology of including QCD next-to-leading-order corrections in the quark-gluon Monte Carlo shower is outlined. The work concentrates on two issues: (i) constructing leading-order parton-shower from scratch, such that it rigorously extends collinear factorization into exclusive (fully unintegrated) one which we call scheme; (ii) introducing (NLO) to hard process this new environment. presented solution designed be extended full NLO-level Carlo, NLO not only but whole shower. issue...
The future 100-km circular collider FCC at CERN is planned to operate in one of its modes as an electron-positron FCC-ee machine. We give overview comparing the theoretical status experimental demands four foreseen operating stages, Z-boson resonance energy physics, called Tera-Z stage for short. will deliver highest integrated luminosities well very small systematic errors a study Standard Model (SM) with unprecedented precision. In fact, allow least more perturbative order quantum field...
A new method of including the complete NLO QCD corrections to hard processes in LO parton-shower Monte Carlo (PSMC) is presented. This method, called KrkNLO, requires use parton distribution functions a dedicated factorization scheme, which also discussed this paper. In future, it may simplify introduction NNLO and PSMC. Details numerical examples its practical implementation, as well comparisons with other calculations, such MCFM, MC@NLO, POWHEG, for single $Z/\gamma^*$-boson production at LHC, are
We present the leading-logarithm (LL) final-state radiative effects for exact $\mathcal{O}(\ensuremath{\alpha})$ YFS exponentiated (un)stable $\mathrm{WW}$ pair production at CERN LEP2 or NLC energies using Monte Carlo event generator methods. The corresponding generator, version 1.12 of program YFSWW3, wherein both standard model and anomalous triple gauge-boson couplings are allowed, generates $n(\ensuremath{\gamma})$ radiation from initial state intermediate ${W}^{+}{W}^{\ensuremath{-}}$...
A bstract Motivated by the regime of QCD explored nowadays at LHC, where both total energy collision and momenta transfers are high, we investigate evolution equations high factorization. In order to study such effects like parton saturation in final states one is inevitably led how combine physics BK CCFM equations. this paper obtain a new exclusive form equation which suggests possible nonlinear extension equation.
Due to the high anticipated experimental precision at Future Circular Collider FCC-ee (or other proposed $e^+e^-$ colliders, such as ILC, CLIC, or CEPC) for electroweak and Higgs-boson measurements, theoretical uncertainties may have, if unattended, an important impact on interpretation of these measurements within Standard Model (SM), thus constraints new physics. Current theory uncertainties, which would dominate total uncertainty, need be strongly reduced through future advances in...

We present precision calculations of the processes e+e- -> 4-fermions in which double resonant W+W- intermediate state occurs. Referring to this latter as 'signal process', we show that, by using YFS Monte Carlo event generators YFSWW3-1.14 and KORALW1.42 an appropriate combination, achieve a physical on signal process, isolated with LEP2 MC Workshop cuts, below 0.5 per cent. stress full gauge invariance our compare results those other authors where appropriate. In particular, sample data...
The concept of new methodology adding QCD NLO corrections in the initial state Monte Carlo parton shower (hard process part) is tested numerically using, as an example, heavy boson production at hadron--hadron colliders such LHC. In spite use a simplified model process, all presented numerical results prove convincingly that basic works correctly practice, environment event generator. differences with other well established methods, like MC@NLO and POWHEG, are briefly discussed future...
We show that already at the NLO level DGLAP evolution kernel Pqq starts to depend on choice of variable. give an explicit example such a variable, namely maximum transverse momenta emitted partons and we identify class variables leave unchanged with respect known standard MS-bar results. The kernels are calculated using modified Curci-Furmanski-Petronzio method which is based direct Feynman-graphs calculation.
