Preliminary but close to final results on the Z lineshape and Forward-Backward asymmetries from the four LEP experiments are presented. Combined values extracted from ALEPH. DELPHI, L3 and OPAL data recorded at energies around the Z pole are discussed.
We examine the O(alpha_s) forward-backward asymmetries for the production process e+ e- --> gamma,Z --> q qbar (g), tagging the outgoing heavy-quark jet at center-of-momentum energies off the Z-peak. The complicated analytic results are reduced to si
We suggest that the forward-backward asymmetry $(A_{FB})$ of the charged leptons in $ggto Htogamma Ztogamma ell^-ell^+$ process could be used to probe the CP violating $Hgamma Z$ coupling when the interference from $ggtogamma Ztogamma ell^-ell^+$ pro
We suggest that the forward-backward asymmetry $(A_{FB})$ of the charged lepton in $ggto Htogamma Ztogamma ell^-ell^+$ process could be used to probe the CP violating $Hgamma Z$ coupling when the interference from $ggtogamma Ztogamma ell^-ell^+$ proc
Precision determinations of Standard Model (SM) Electro-Weak (EW) parameters at the Large Hadron Collider (LHC) are dominated by uncertainties due to Parton Distribution Functions (PDFs). Reweighting and profiling techniques are routinely employed to
We address the impact of future measurements of charged and neutral current Drell-Yan (DY) asymmetries and their combination on Parton Distribution Functions (PDFs) uncertainties. We quantify the reduction of PDF uncertainties using the QCD tool xFit
