The high energy proton collider, the LHC machine at CERN, Geneva, has delivered a few collisions at the centre of mass energy of 13 TeV (13 million million electron-Volts) recently for the first time ever and thus broken its own record of Run1 (collisions at 7 and 8 TeV during 2010-12). By April 10 proton beams at LHC reached the energy of 6.5 TeV, and, by May 5 low energy collisions (900 GeV) were recorded by all the experiments. Recently the machine has been tuned well and it has started delivering good quality collisions on June 3. Analyzing this data physicists expect to peer into the secrets of the early universe. Members of the TIFR-CMS group are taking part in data collection, monitoring and analyses. During the shutdown period after Run1, which lasted for about two years (2013-14), the machine as well as the experiments were consolidated to meet the challenges of the current phase (Run2). The TIFR group participated in this upgrade of the CMS experiment. The Run1 of the LHC machine has been highly successful with the discovery of the Higgs boson of mass 125 GeV by ATLAS and CMS experiments in 2012 that led to the 2013 Nobel Prize in Physics to Peter Higgs and Francois Englert. Stay tuned during Run2 which will last for more than two years as large volumes of high-quality data will bring in exciting news from LHC!
