The work of a Jaipur physicist on the standard model of particle physics, explaining new aspects of dark matter, dark energy and disappearance of anti-matter in the Universe, has been recognised by Belle Collaboration, an international body of more than 400 physicists and engineers, head quartered at the High Energy Accelerator Research Organisation, Tsukuba, Japan.
Physicist Dinesh Kumar and his team has provided “tantalising hints” of laws of nature beyond the current theory of Higgs boson, also referred to as the elusive God particle. Dr. Kumar has made measurements that cannot be explained by the standard model and are related to the decay of a sub-atomic particle known as “beauty meson”.
Dr. Kumar, who earlier taught at Rajasthan University, is currently with the National Centre for Nuclear Research, Warsaw, Poland. The findings of his research, which started in 2016, have been confirmed by Belle Collaboration. The work was earlier published in the journal Physical Review-D .
Dr. Kumar told The Hindu from Warsaw that his work has helped solve “puzzles on new interactions of nature” by seeking to explain the disappearance of anti-matter in the universe. He said this decay could not be explained by the standard model.
“A breakthrough has been achieved in our experiments, which have found that these new interactions can be confirmed or ruled out if we are able to measure the charmed meson’s polarisation,” he said.
