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).
