CERN Accelerating science

CMS experiment

Three years after the announcement of the discovery of a new particle, the Higgs boson, the ATLAS and CMS Collaborations have recently presented for the first time combined measurements of many of its properties...

CMS results in Hard Probes 2015

by Olga Evdokimov & Camelia Mironov

CMS has delivered a comprehensive set of differential RAA measurements, quantifying the jet quenching effect for hard probes of various flavors. Profound suppression of strongly interacting probes in 2.76 TeV PbPb collisions is established with high precision for inclusive charged hadrons, spanning the wide range of transverse momenta from soft-sector all the way up to 100 GeV/c, and inclusive fully reconstructed jets, that remain quenched even at 300 GeV/c.

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. 

 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.

Last month, the High Energy and Particle Physics division of the European Physical Society announced the 2015 prizes for outstanding contributions in the field of high energy physics.

CMS: LS1 – A Short Summary and an Outlook to the Endgame

by Wolfram Zeuner, CMS Deputy Technical Coordinator

Following a long programme of upgrades and improvements, CMS will be perfectly prepared for the exciting times ahead of us, with the LHC providing collisions of unprecedented energy and luminosity.

CMS tests new Resistive Plate Chambers

by Imad Laktineh

The new Resistice Plate Chambers (RPCs) will play an important role in the CMS trigger systems in the light of the LHC future runs. 

RD53: Development of pixel readout integrated circuits for extreme rate and radiation.

by Jorgen Christiansen and Mauricio Garcia-Scriveres on behalf of the RD53 Collaboration

The recently formed RD53 collaboration will address the challenges of phase 2 pixel detector upgrades of ATLAS and CMS as well as long-term challenges for LCD.
