Dr. Sudip Jana, a former OSU PhD in physics and postdoctoral researcher in theoretical physics at the Max-Planck-Institut für Kernphysik, Germany, and Vishnu PK, currently a PhD in physics at OSU, and two other collaborators have had their research accepted for publication in Physics Review Letters.

Jana and Vishnu PK collaborated with Johannes Herms of the Max-Planck-Institut für Kernphysik, Germany and Shaikh Saad of the Department of Physics, University of Basel, Basel, Switzerland. Their research focuses on a new model of dark matter (DM) with favorable implications for defining the currently unrecognized component of the universe – the discovery of such a method may advance knowledge of the universe.

“The mass of DM should be very close to the mass of leptons, which can potentially be identified from annihilation of DM in gamma rays,” Jana said. “We show that the phenomenon of neutrino oscillations is intrinsically linked to the observed abundance of DM relics. The new physics involved in our framework is at or below the electroweak scale, making it testable in upcoming colliders, beam dump experiments, and future sub-GeV gamma-ray telescopes. This will be of great interest to the particle and astroparticle physics community.

Jana said that since he did his PhD in Theoretical Physics at OSU under Dr. KS Babu, Professor Regents and Theoretical Physicist, the Department of Physics has played an important role in his research career. Jana continued to collaborate with OSU colleges and supervise and mentor several graduate students – one being Vishnu PK

“The guidance provided by Dr. Babu and several advanced courses offered by the department prepared me to participate in research at an early stage of my graduate studies,” said Vishnu PK. “I was lucky to have good support from my senior colleagues; they guided me and collaborated with me on several research projects. Dr. Jana and I have collaborated on 10 research articles published in well-known peer-reviewed journals, including the current article.

The Max-Planck-Institut für Kernphysik, Germany, and the OSU High Energy Physics Group have built a strong research collaboration. Jana said he has a strong attachment to OSU’s physics department.

“OSU students and alumni do cutting-edge research in theoretical physics and publish their research in top peer-reviewed journals, which can inspire current and future students,” Jana said. “This research paper focuses on light thermal dark matter, which makes up a huge quarter of the universe’s energy budget.”
