In recent years, Indian scientists have been involved in all pioneering activities at CERN. India has made significant contributions to the construction of the Large Hadron Collider (LHC), in the areas of design, development and supply of hardware accelerator components/systems and its commissioning and software development and deployment in the machine.

India is one of the leading partners in the ALICE experiment, which is on a quest to unearth the physics of quark-gluon plasma (QGP) and to get a glimpse of how matter behaved within a few microseconds after the birth of our Universe.

The discovery of the Higgs Boson at the LHC is the most talked about scientific discovery in recent memory. Indian scientists have played a significant role in the Compact Muon Solenoid (CMS) experiments, which is one of the two large experiments that have led to the discovery of the Higgs Boson. Indian scientists have been named as part of this historic discovery. This helps India in participating in the high end technology related to high energy accelerators.

It is noteworthy to mention the involvement of Indian scientists in high-tech particle detectors and electronics research, ISOLDE and n-TOF experiments, and various application oriented programmes including medical imaging. In the field of large-scale computing, India has made major contributions in terms of designing, developing and deploying software for the Worldwide Large Hadron Collider Grid (WLCG).

It is worth mentioning that the grid Tier2 centers established at Variable Energy Cyclotron Centre (VECC), Kolkata and Tata Institute of Fundamental Research (TIFR), Mumbai have provided the pledged resources and are operating with 96% uptime, thereby facilitating running of computational jobs by various CERN collaborations.
