The top quark is the heaviest known fundamental particle. As it is the only quark that decays before it hadronizes, this gives us the unique opportunity to probe the properties of bare quarks at the Large Hadron Collider. This talk will present highlights of a few recent precision measurements by the ATLAS Collaboration of the top quark using 13 TeV and 8 TeV collision data: top-quark pair and...

We have studied the sensitivity of the CMS and LHCb experiments to lepton number violating decays of two b-hadrons: $\Lambda^{0}_{b}$ and $B^{0}_{s}$. We focus in the decay channels with two muons and additional hadronic activity. We show that the two experiments are sensitive to this type of process using the current luminosity recorded by them but also we show the perspectives for future...

BESIII is operated at the Being electron positron collider (BEPCII), which reaches a peak luminosity of 1.0x10^33 /cm^2/s at the center-of mass energy of 3770 MeV. With the world’s largest sample accumulated in the tau-charm region of e+e- collision, the recent results for charmonium decays will be presented.

The Belle II experiment is the next generation of B-factory experiment at KEK in Tsukuba, Japan. The construction of the SuperKEKB accelerator and the Belle II detector is now in progress and is aiming for the first physics run in 2018. In the presentation, the key physics goal of the experiment and the current status of the accelerator and the detector will be reported.

Two recent results on the time-dependent CP violation in $b \to c \overline{u} d$ transitions are discussed. The first one is joint Belle and BaBar analysis of the $\overline{B}{}^0\to D^0_{CP} h^0$ decays, where $h^0$ is a light unflavored meson and $D^0$ meson is reconstructed in a CP specific final state. The second one is analysis of the $\overline{B}{}^0\to D^0 h^0$, $D^0 \to...

Recent results of the search for multi-quark exotic states with c- and b-quarks at DZero experiment (FNAL, USA) are presented in this talk. This includes an evidence of the possible tetraquark state X(5568) decaying to B_s \pi in the channels with hadronic and semileptonic decay of B_s meson and a search for the possible pentaquark states in J/\psi \Lambda invariant mass spectrum.

The one of main goals of the LHCb experiment is the measurement of the mixing-induced CP-violating phase phi_s in the Bs-Bsbar system. It has been measured exploiting the Run l data set, using several decay channels. The most recent results obtained analyzing Bs0->J/psi K+K- candidates in the K+K- mass region above the phi(1020) resonance are presented. However, the precision of phi_s is still...
