Research Summary : April 2002 - March 2003

  • New results have been found in the ongoing project on the search for physics beyond the standard model via vector boson fusion (VBF) at the Large Hadron Collider. It has been established that this class of processes are of considerable advantage in exploring the non-strongly interacting sector of various supersymmetric scenarios. Further investigations are in progress, both in the context of supersymmetric theories and theories with large extra dimensions, using different techniques in collider-related calculations (Biswarup Mukhopadhyaya, Anindya Datta, Debajyoti Choudhury, Partha Konar, Katri Huitu, Stefano Moretti).

  • A study on detecting invisible superparticles at linear colliders has been completed. It has been shown that the laser back-scattering facility at such colliders can be of special advantage in this connection (Biswarup Mukhopadhyaya, Debajyoti Choudhury).

  • The possibility of exploring large extra dimensions at a high-energy electron-positron collider has been investigated. It has been shown that Bhabha scattering with the simultaneous radiation of gravitons can yield a lot of useful information about the theory propounded by Arkani-Hamed, Dimopoulos and Dvali (ADD) (Biswarup Mukhopadhyaya, Sukanta Data, Partha Konar and Sreerup Raychaudhuri.

  • It has been found that the presence of the radion field in a Randall-Sundrum Scenario can enhance Higgs production rate. The implications of such resonant enhancement has been investigated in the context of the Large Hadron Collider (Prasanta Kumar Das and Biswarup Mukhopadhyaya).

  • Physics beyond the standard model of electroweak interactions can lead to the Higgs boson(s) being states without definite parity. The implications of such a situation in relation to the observables at linear electron-positron colliders in under investigation (Biswarup Mukhopadhyaya, Debajyoti Choudhury, Ritesh Kumar Singh).

  • The project related to some theoretical aspects of gravity in the presence of spacetime torsion has yielded a few interesting why results. One of these pertain to an ostensible justification of spacetime may appear to have curvature but no torsion, given in the framework of a Randall-Sundrum scenario. Further investigations of this and related scenarios are in progress (Biswarup Mukhopadhyaya, Somasri Sen, Soumitra Sengupta).
