We show using a model independent approach that the deviation in measured B_d^0-\bar{B}_d^0 mixing phase caused by pollution from another amplitude, within the Standard Model, is always less in magnitude, and has the same sign as the weak…
Precision measures of electroweak and flavour observables, at both low and high energies, are highly complementary to direct searches for New Physics at high-energy colliders. Despite the discovery of the Higgs boson at the Large Hadron…

We estimate, in a large class of scenarios, the sensitivity to new physics in B_d and B_s mixings achievable with 50 ab-1 of Belle II and 50 fb-1 of LHCb data. We find that current limits on new physics contributions in both B_{d,s} systems…

We review recent B physics results from the CDF and Dzero experiments in p-pbar collisions at sqrt(s) = 1.96 TeV. Using a data sample of 1.4-6.0 fb-1 collected by the CDF II detector we present searches for New Physics in Bs sector and some…

We have just entered a new round in the testing of the flavour sector of the Standard Model through high-precision measurements of B-meson decays. A particularly exciting aspect is the exploration of the B_s-meson system at LHCb. We focus…
Measurements of diboson events in proton-antiproton collisions at $\sqrt{s}=1.96$ TeV are effective probes of the electro-weak gauge structure in the Standard Model (SM). Due to the potentially high energy scale in the collisions, bosonic…
The exploration of B-meson decays has reached an unprecedented level of sophistication, with a phase of even much higher precision ahead of us thanks to run 2 of the LHC and the future era of Belle II and the LHCb upgrade. For many…
Several models of dark matter motivate the concept of hidden sectors consisting of SU(3)_C x SU(2)_L x U(1)_Y singlet fields. The interaction between our and hidden matter could be transmitted by new abelian U'(1) gauge bosons A' mixing…
