Electroweak double-logs at smallx

Electroweak Double-logs at Small X

We investigate enhanced EW corrections to inclusive hard processes in the TeV energy region with emphasis on the small-x situation, in which the hard scale Q is significantly smaller than the available energy √ s ≡ Q/x. We first propose and justify a general factorization formula in which the (double-log) EW form factor at scale Q is factorized from EW parton distribution functions, which satis...

Electroweak Physics at LHCb

Electroweak Physics at Lep2

The measurements resulting from the analysis of the LEP2 data have brought more strong evidence in support of the standard electroweak model. In particular the LEP2 data has revealed (i) the first determination of the SU(2) gauge bosons self-couplings, (ii) the first direct measurements of the W decay-couplings, and (iii) the current best direct measurement of the W mass.

Electroweak Physics at LHC

The Large Hadron Collider, LHC, though meant for discovery, will provide enough data from early phase to also perform various studies of Standard Model processes in as yet unexplored kinematic regions. Precision measurements of the electroweak variables will be possible due to the large rates of W and Z boson productions combined with clean leptonic signatures. Examples of simulation results fr...

Electroweak Measurements at Tevatron

Recent Run 2 experimental results on electroweak physics from the CDF and DØ collaborations at Tevatron are reviewed. We present measurements of the inclusive W and Z boson cross-sections times leptonic branching ratio as well as the Z/γ forward-backward asymmetry and the W charge asymmetry for pp̄ collisions at √ s = 1.96 TeV . The first Run 2 studies for the W width and W mass measurements are...
