Measurement of jet multiplicity distributions in t-tbar production in pp collisions at sqrt(s) = 7 TeV / CMS Collaboration
The normalised differential top quark-antiquark production cross section is measured as a function of the jet multiplicity in proton-proton collisions at a centre-of-mass energy of 7 TeV at the LHC with the CMS detector. [...]

Observation of the resonant character of the $Z(4430)^-$ state
Resonant structures in $B^0\to\psi'\pi^-K^+$ decays are analyzed by performing a four-dimensional fit of the decay amplitude, using $pp$ collision data corresponding to $\rm 3~fb^{-1}$ collected with the LHCb detector. [...]

Spectator Effects during Leptogenesis in the Strong Washout Regime / Garbrecht, Bjorn ; Schwaller, Pedro
By including spectator fields into the Boltzmann equations for Leptogenesis, we show that partially equilibrated spectator interactions can have a significant impact on the freeze-out value of the asymmetry in the strong washout regime. [...]
