LHCb experiment

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.

During, the 7th edition of the Hard Probes International Conference series was hosted by McGill University in Montréal, Canada, the LHC experiments presented a wealth of scientific results from heavy-ion collsions at the LHC. 

In the recent EPS conference, LHCb presented results from Run2 of the LHC, confirming that a certain decay involving the weak force happens with beauty quarks having a “left-handed” spin. This result is consistent with the SM, in contrast with previous measurements that allowed for a right-handed contribution.

 We asked the Data Quality Monitoring teams of the four major LHC experiments to present the tools they are using and how the DQM is organized to fit the specifications of each detector.

 LHC experiments have released a portion of its data to the public for use in education and outreach as part of CERN's policy of openness.

In the previous issue of the PH Newsletter, we introduced the Run Coordinators of CMS, LHCf, and ALICE. This time, we will get to know the Run Coordinators of ATLAS, TOTEM, and LHCb, who talk about their work and the challenges that they have to face.

Injection tests make a splash

On Saturday 7 March, two of the LHC experiments saw proton beams for the first time after a two-year stop

LHCb gears up for Run2

by Rolf Lindner: Technical Coordinator, LHCb experiment

It is now 18 months that LHCb has not seen any particle beam passing through the experimental area, and the collaboration is eagerly waiting for the start-up of Run II in spring 2015.

LHCb is developing a new tracking detector for installation during Long Shutdown 2.
