At the LHC, Prof. Ashutosh Kotwal is heading up the ATLAS experiment's research team on searches for Zprime bosons. In August this ATLAS group submitted a new paper on this research to Physical Review Letters. This is the world's most sensitive search for Zprime bosons, which are new kinds of particles predicted in theories of force unification. Prof. Kotwal's team has also searched for Gravitons, which are massive particles hypothesized to mediate the force of gravity and explain why gravity is so much weaker than other forces.
