LHCb experiment

New data from B decays recorded in the LHCb experiment challenge lepton universality.  

A wealth of new results from the LHC experiments was presented in the 52 edition of the Moriond conference. 

Wealth of new results in Quark Matter 2017

by Panos Charitos

Last month, the LHC experiment collaborations presented their latest results at the Quark Matter 2017 conference on how matter behaved in the very early moments of the universe.

The LHCb collaboration recently published in Nature Physics the first evidence for the violation of the CP symmetry in baryon decays.

LHCb searches for CP violation

by Monica Pepe Altarelli

LΗCb has been performing many accurate measurements of CP-violating asymmetries in processes involving beauty- and charm-hadron decays to determine whether they are consistent with the CKM mechanism or whether new physics should be invoked to explain them.

Thanks to the outstanding performances of the LHC, the experiments presented a wealth of new results in ICHEP2016.

LHC Restart 2016

by Panos Charitos

Following the 2016 restart of the LHC, we have asked the run coordinators of the four largest LHC experiments — ALICE, ATLAS, CMS and LHCb — to share a few words with us about the first data taking. Their broad physics programme will be complemented by the measurements of three smaller experiments (TOTEM, LHCf and MoEDAL) and may hold the key to new physics.

A successful year for the LHCb collaboration

by Patrick Robbe

After the Long Shutdown 1, the LHCb experiment started data taking during this year both during the proton-proton collisions at 13 TeV but also for the first time during the heavy-ion run.

LHC experiments upgraded trigger plans

by Panos Charitos

As the LHC prepares for higher energies and luminosities all four experiments have upgraded their triggering to record data more efficiently and make sure that their detectors are ready to find evidence for new physics.

At the 7th edition of the Hard-Probes conference, taking place at McGill University, Montreal, from June 29 - July 3, the LHCb collaboration presented for the first time its plan and potential in heavy ion physics. Beyond the rich programme in flavour physics based on proton-proton collisions, LHCb has participated so far only in the proton-lead run of 2013, but not in the lead-lead runs of 2010 and 2011. The reason has been/was that the detector occupancy in the forward region for central lead-lead collisions is too large.
