/**/ The CMS experiment has submitted a paper for publication describing the first observation of a new, excited bottom (or beauty) baryon known as the Ξ*b0, with a statistical significance of more than 5 standard deviations (5σ) above the…

No, unfortunately not yet the discovery of the century. Still, the new particle found by CMS in its 2011 dataset is a very important piece of the puzzle of low-energy spectroscopy. Here "low" should be taken with a pinch of salt: the new particle,…

The Year-End Technical Stop or YETS, when the LHC takes its annual break, seemed like a quiet time to those outside CERN. After all, there were no collisions taking place and the CMS detector was not operating 24-hours-a-day, seven-days-a-week.…

A new year with new energy and new luminosities: 2012 holds the promise to close the question on the existence (or absence) of a Standard Model Higgs boson. Besides the obvious challenges posed by the LHC restart at a higher energy and a much…

As high-energy particle physics pushes exploration at energy and luminosity frontiers, experiments are becoming increasingly complex – and this, in turn, drives the need for developments in particle detectors and their associated technologies.…

The Large Hadron Collider has woken from its winter slumber with a bang. Just after midnight local time on 5 April, the world's most powerful particle accelerator, based near Geneva, Switzerland, shattered its own world record by smashing protons…

A search is presented for a massive particle, generically referred to as a Z′, decaying into a t-tbar pair. The search focuses on Z′ resonances that are sufficiently massive to produce highly Lorentz-boosted top quarks, which yield collimated decay…

The production of b jets in association with a Z/γ* boson is studied using proton-proton collisions delivered by the LHC at a centre-of-mass energy of 7 TeV and recorded by the CMS detector. The inclusive production rates for Z/γ* + b-jet is…
