The first simultaneous test of muon-electron universality using B+→ K+ ℓ+ ℓ-and B 0→ K* 0
ℓ+ ℓ-decays is performed, in two ranges of the dilepton invariant-mass squared, q 2. The …

The first simultaneous test of muon-electron universality using B+→ K+ ℓ+ ℓ− and B0→ K*
0ℓ+ ℓ− decays is performed, in two ranges of the dilepton invariant-mass squared, q2. The …

A simultaneous analysis of the B+→ K+ ℓ+ ℓ-and B 0→ K* 0 ℓ+ ℓ-decays is performed to test
muon-electron universality in two ranges of the square of the dilepton invariant mass, q 2 …

Evidence for pair production of a new particle consistent with the standard-model top quark
has been reported recently by groups studying proton-antiproton collisions at 1.8 TeV center …

Global fits for precision determinations of parton distributions, together with the highly
correlated strong coupling α s, are presented up to next-to-next-to-leading order (NNLO) of …

We present a new analysis of parton distributions of the proton. This incorporates a wide
range of new data, an improved treatment of heavy flavours and a re-examination of prompt …

We calculate the complete electroweak O (α) corrections to pp (−)→ l+ l− X (l= e, μ) in the
standard model (SM) of electroweak interactions. They comprise weak and photonic virtual …

W and Z bosons will be produced copiously at the LHC proton-proton collider. We study the
parton distribution dependence of the total production cross sections and rapidity …

We discuss a model in which the third generation fermions undergo a different SU (2) weak
interaction from the first two generation fermions. In general, a flavor changing neutral …

A bstract The production of Z bosons is studied in the dimuon and dielectron decay channels
in PbPb and pp collisions at\(\sqrt {s_ {NN}}= 2.76\) TeV, using data collected by the CMS …
