Research Proposal:


I aspire to be a High Energy physicist. I would like to work in the branches of High energy physics - Theory or Phenomenology. In my B.Sc (Physics) 3 year course in Jadavpur University I learnt all the basics of Modern Physics. After joining Cambridge University I came to know more about these subjects in detail. In the Part II (Theoretical Physics) course I learnt the topics like Scattering theory, Perturbation theory, Path Integral, Identical Particles and Density Matrices which have many applications in different parts of particle physics.

In my present year (Part III) I did a course on Experimental and Theoretical Particle physicsin the last term where I learnt about Symmetries in the Standard Model, Feynmans Parton Model and Bjorken scaling. Towards the end we were exposed to the concept of Supersymmetry. In this term I am attending the lectures on Frontiers in Particle Physics which will help me know about the current experiments going on world wide. I am going for courses on Quantum Field Theory which help in understanding the Feynman Diagrams and determining the scattering cross-sections. In this term I am learning the gauge field theory as well.

In the last year while writing a review paper on "Neutrino oscillation: Atmospheric Neutrinos" under the supervision of Prof. Bryan Webber, Head of the Theoretical High Energy Physics group of Cavendish Laboratory I went through lots of recent publications on this subject, including the recent observation at Super-Kamiokande and MINOS. This helped me a lot to have an experience of studying the current research works of the people around the world. At that time I came to know a lot about discovery of the neutrino, its properties and the recent discovery regarding the probable neutrino mass that opened a new area of interest for me. I want to do some theoretical work regarding this neutrino mass anomaly.

In the last summer I completed a project on " A Note on the neutrino mass implication of the K2K experiment" under the guidance of Prof. Amitava Raychaudhuri, Head of the Department and Taraknath Palit Professor in Physics at the University of Calcutta, India. The article got accepted for publication in "Journal of Physics G: Nuclear and Particle Physics" as a paper. ( The work can be found in the arXiv: hep-ph/0303229) We studied the first result published by K2K group on the observation of mu-neutrinos. They show a depletion compared to the expectation and are consistent with neutrino oscillation with a mass-splitting in the range favoured by the Super-Kamiokande atmospheric neutrino measurements. We examined the extent by which the range of mass-squared difference obtained from the K2K can vary due to the uncertainties in the flux, cross-section and detector efficiency.

Right now the data for the range of mass of neutrino is available. I intend to work on determination of precise neutrino mass and thereby modification of the standard model resulting in a new physics. I look forward to doing some simulation work related to testing of data obtained from different experiments like MINOS. Having the experience to work in both Fortran and C and little bit of C++ I hope I could be of some use to the groups involved in the computational works in High Energy physics. I have interests in analysing data obtained from recent high-energy measurements of nucleon scattering at the HERA accelerator. I shall be happy to be a part of the programme which aims at testing the standard model and of identifying new phenomena. The very question: Why is the electroweak scale so much smaller than the scale used in Gravitational calculations? fascinates me a lot. I want to learn more about supersymmetry which is the way to link between Fermions and Bosons two fundamentally different types of particle in nature. I have interests to work on CP and CPT violation, theoretical calculations leading to prediction of neutrino mass and studies of the structure of the nucleon, too.
