Siginificant Contribution of Indians in God Particle Discovery

The historic discovery of a new subatomic particle has a significant India connection. Scientists from Delhi University collaborated with Bhabha Atomic Research Centre (Barc) in the development of 1,000 silicon microstrip detectors for the Compact Muon Solenoid (CMS) experiment. Scientists from Kolkata's Saha Institute Of Nuclear Physics (SINP), Panjab University and Tata Institute of Fundamental Research pitched in with equipment and research.

Indian teams were involved from the inception of the project. Principal investigator of the project and the head of the DU group, Dr R K Shivpuri, said that Indian groups made part of the calorimeter used to measure the energy of particles. "In 1995, the Indian groups had decided to participate in detector fabrication in two areas: silicon strip detector based preshower detector (Si-PSD) of CMS and plastic scintillator based outer hadron calorimeter (HO). DU and Barc participated in Si-PSD and Tata Institute of Fundamental Research and Punjab University participated in the HO project. These detectors were made in India and taken to Cern and installed as part of the CMS detector. These detectors are taking data and are being maintained and operated by the Indian team," said Shivpuri.

The DU team includes teachers from the university's physics department, Kirti Ranjan, Ashok Kumar and Ashutosh Bhardwaj. Eight PhD scholars from DU are involved in the project.

Scientists from Kolkata's Saha Institute of Nuclear Physics (SINP) made significant contributions to the development of the CMS experiments at Cern, said director Milan Sanyal. Stating that it was a historic moment in physics and SINP took pride in being a part of the history, he said "It will require more data and intense scrutiny to establish these findings beyond any doubt...This is an important moment for the development of science," Sanyal said.
