The discovery of a new sub-atomic particle that is crucial to understanding how the universe is built has an intrinsic Indian connection.
A large number of Indian scientists were involved in the world’s most ambitious experiment over the years.
The Indian scientists represent the Saha Institute of Nuclear Physics (SINP), Kolkata, Tata Institute of Fundamental Research, Mumbai, Harishchandra Research Institute, Allahabad and Institute of Physics, Bhubaneswar.
The Indian link to the world’s ambitious experiment was also significantly reflected in comments ahead of the announcement by CERN scientists that a sub-atomic particle “consistent” with the Higgs boson or ‘God particle’ has been spotted.
“India is like a historic father of the project,” said Paolo Giubellino, spokesperson of Geneva-based European Organisation for Nuclear Research, famously known as CERN.
As scientists thrashed out the ‘God particle’ in its physical form in a giant collider, there was palpable excitement at SINP whose scientists had made significant contributions to the development of the Compact Muon Solenoid (CMS) experiments at CERN.
The long-sought particle, known as Higgs boson, is also partly named after an Indian scientist Satyendra Nath Bose, who worked with Albert Einstein in the 1920s and made discoveries that led to the most coveted prize in particle physics.
SINP director Milan Sanyal says more data and intense scrutiny are required to establish these findings beyond any doubt.
“This is an important moment for the development of science and I am very happy that our institute, this city and our country is part of the science revolution,” he said.
He said that the core CMS team of the SINP had five faculty members — group leader Prof Sunanda Banerjee, Prof Satyaki Bhattacharya, Prof Suchandra Datta, Prof Subir Sarkar and Prof Manoj Saran.
The phrase “God particle” is a corruption of Goddamit. Nobel Prize- winning physicist Leon Lederman once dubbed it the “goddamn” particle, because it has proved so hard to isolate.
That name was changed by an editor to the “God” particle, and the name has stuck on.
The name Higgs Boson came from a British scientist Peter Higgs and Bose, who studied at Presidency College, Calcutta.
The work done by Bose and Albert Einstein, later added by Higgs, led to this pioneering day.
The fact that only the “H” in Higgs boson is capitalized in most cases has been a subject matter of debate among the Indian scientific fraternity.
Sanyal said most of his team members at Geneva had worked for more than a decade with the CMS experiment with notable contributions in the development of the experiment right from the early stage and were actively participating in the analysis of the incoming data.
SINP is the oldest institute in the area of nuclear physics in India.
He said the SINP had joined in the CMS experiment at the Large Hadron Collider facility through a memorandum of understanding with CERN signed in Kolkata during the last visit of the CERN Director-General.
Meanwhile, another Indian facility Indore-based Raja Ramanna Centre for Advanced Technology (RRCAT) has also played a role in the spotting of the sub-atomic particle.
RRCAT, a Department of Atomic Energy (DAE) facility, has supplied vital parts for Large Hadron Collider (LHC) of European Organisation for Nuclear Research (CERN).
It was the nodal agency from the DAE for the ambitious LHC project, sources associated with the project at the institute said.
Besides RRCAT, Indore based Indo-German Tool Room (IGTR) also played a major role in the development of Jacks on which the 27-km long LHC is positioned, IGTR Manager, Consultant and Marketing, C S Sharma said.
Under an agreement of DAE and CERN, Centre for Advanced Technology developed a number of subsystems for the world’s largest particle accelerator — the Large Hadron Collider (LHC), the sources said.
