     Unlike the standard model of particle physics, string theory is based on the assumption that the fundamental objects of nature are one-dimensional. These objects known as strings are assumed to have a length of the order of 10^-34 cm (Planck length). Modern accelerators can only probe down to distance scales around 10^-16 cm and hence these strings look like point particles.

      The basic assumption of string theory although very simple, results in remarkable physical consequences such as; reconciliation of quantum mechanics and general relativity, prediction of extra dimensions and demand for supersymmetry, quantum description of black holes, holographic description of gravity, etc.

 The string theory group of IPM consists of :
