Electroweak and searches/heavy flavours
I present recent calculations of observables in top quark pair production at hadron colliders, including the total cross section, the invariant mass distribution, the transverse momentum and rapidity distributions, and the forward-backward asymmetry. The calculations are based on the resummation of threshold logarithms at NNLL accuracy beyond NLO.

Electroweak and searches/heavy flavours
We present the result of a measurement of single top-quark production
in the t-channel at 7 TeV proton-proton collisions with the ATLAS
detector at the Large Hadron Collider. A lower limit on the CKM matrix
element |Vtb| is extracted from this measurement. The single-top quark
production in the Wt- and s-channels is also explored.

Electroweak and searches/heavy flavours
Several searches of physics beyond the standard model involving top
quarks in the final state are presented. These searches encompass top
decays in FCNC channels, resonances decaying in ttbar final states,
new heavy quarks decaying to top quarks, production of same-sign
quarks, and recent tests of various new physics models.

Electroweak and searches/heavy flavours
The kinematic properties of the data used for the measurement
of the top-antitop quark pair production and of the single top
quark production cross sections are used to set constraints on
a variety of signals of physics beyond the SM. We set constraints
on possible 4th generation top quarks, on possible resonances
that would decay into top-antitop quark pairs, on possible
resonances that...

Electroweak and searches/heavy flavours
Following recent intriguing experimental results on top quark pair production from the Tevatron I review the present status of new physics explanations put forward to explain the experimental observations deviating from standard model predictions. All proposals face severe constraints from precisely measured flavor, electroweak and high pt collider observables. Possible future measurements at...

Electroweak and searches/heavy flavours
We report recent results from indirect searches for BSM physics using flavor processes in the
whole sample of 9.6 fb^-1 collected by CDF in Tevatron Run II. These include the final measurements of flavor-changing-neutral-current, rare B-> mu^+ mu^- and B-> K mu^+ mu^- decays, the final measurements of the bottom-strange mixing phase (phi_s) using Bs->J/Psi Phi decays, measurements of the...
