GUWAHATI, March 5 - The Department of Physics of Assam University, Diphu Campus (AUDC) celebrated the National Science Day in association with the Physics Academy of North East (PANE) at Diphu recently.

To celebrate the occasion and to pay tribute to Sir CV Raman for his immense contribution to science in general and to Physics in particular, informative talks on two topics were held.

The first talk was delivered by Dr Bipul Bhuyan, Associate Professor of IIT, Guwahati and the general secretary of PANE on the topic �Neutrino: An Elusive Subatomic Particle.� At the beginning, Dr Bhuyan explained how neutrinos are the most elusive particle in the Standard Model (SM) of particle physics. Hypothesized as a particle never to be found, the neutrinos have consistently kept the physicists engaged in understanding the fundamental nature of this particle in the last several decades.

�With the experimental detection of this particle, followed by the establishment of the phenomena of neutrino oscillation in the recent years, scientists have come a long way in uncovering the mysteries of this particle,� he said and elaborated how from solar and atmospheric neutrino oscillations, the squared differences in the masses of any two flavours have been determined, but the absolute values of masses of three different flavours of the neutrino are still to be determined.

In the second talk, Dr Pijush Kanti Dhar, Associate Professor of Arya Vidyapeeth College, Guwahati and publicity secretary of PANE talked on the extra-terrestrial Ultra High Energy (UHE) neutrinos coming from long distance and how they are detected in IceCube neutrino Telescope in the Antarctica.

He explained how such neutrinos, which are unique astronomical messengers, get detected in the deep core of the IceCube observatory by interacting with the ice. With animation videos, he displayed how the Cerenkov radiation is emitted by particles formed by interactions of neutrino with nucleons and how such a radiation forms tracks and showers in the IceCube.

�The observation of good number cosmogenic neutrinos by high energy astrophysical neutrino observatory IceCube had created a lot of current interest in neutrino astronomy that has led to most striking experimental results,� he said.

Earlier, a wall magazine was released by Dr Bipul Bhuyan. Prof Ranjit Sinha, the HoD of Physics of AUDC gave the welcome speech.
