    The Compact Muon Solenoid experiment at the CERN Large Hadron Collider will study protonproton collisions at unprecedented energies and luminosities. In this article we providefi rst a brief general introduction to particle physics. We then explain what CERN is. Thenwe describe the Large Hadron Collider at CERN, the most powerful particle acceleratorever built. Finally we describe the Compact Muon Solenoid experiment, its physics goals,construction details, and current status.

    A specific research and development programme was undertaken by BARC, to develop the technology for 32-strip silicon sensors, for the Compact Muon Solenoid (CMS) experiment at the Large Hadron Collider (LHC), CERN. These sensors will be used as Preshower sensors in the Electromagnetic Calorimeter of CMS for π/γ rejection and will cover an area of ~40,000 cm in the CMS. Developing silicon sensors with very stringent electrical specifications and uniformity over a large area of ~ 40 cm has been a challenging task, as such technology did not exist in our country. This R&D has been carried out in various phases such as prototype development, preproduction and production. Figs.1, 2 and 3 show wafers fabricated during various phases ofthis project.

    After a brief overview of the Compact Muon Solenoid (CMS) experiment, the status of construction, installation and commissioning is described. Very good progress has been achieved in the past year. Though many significant challenges still lie ahead, CMS should be ready for recording data from first collisions in the Large Hadron Collider (LHC) accelerator complex at CERN

    The success of the first three years of operations of the LHC at center-of-mass energies of 7 and 8 TeV radically changed the landscape of searches for new physics beyond the standard model and our very way of thinking about its possible origin and its hiding place. Among the paradigms of new physics that have been probed quite extensively at the LHC, are various models that predict the existence of extra spatial dimensions. In this review, the current status of searches for extra dimensions with the CMS detector is presented, along with prospects for future searches at the full energy of the LHC, expected to be reached in the next few years.
