Direct coupling of the Higgs boson to the top quark observed
An observation made by the Compact Muon Solenoid experiment at the Large Hadron Collider at CERN, published in the Physical Review Letters today, connects for the first time the two heaviest elementary particles of the Standard Model. Members of the CMS collaboration, including the Excellence of...

NA62: First results on $K^+\to \pi^+ \nu\bar{\nu}$.
On Sunday 11th of March, NA62 collaboration presented in Moriond the first results of the $K^+\to \pi^+ \nu\bar{\nu}$ analysis. This channel has a branching ratio in the SM of (8.4 ±1.0) × 10-11.
The analysis presented in Moriond is based in the study of a sample of 1.21× 10-11...

Tracing the path from Tevatron to LHC
On Tuesday, 4th of April, at the 25th DIS international workshop in Birmingham, UK, the CMS experiment extended the very first cross section measurement of the top pair (tt) production at 5.02 TeV center-of-mass (c.o.m) energy. The measurement tracks the evolution of the tt cross section as a...
