Large Hadron Collider (LHC) is offering a whole new ground for subatomic studies in the Tevatronenery regime. Elastic scattering is explored by the TOTEM Experiment which will offer us a clearer picture of diffractive scattering. Together with earlier measurements at GeV energies, theory faces a challenge. In our recent work, it was observed that by using Generalized Chou Yang model we can give a consistent picture of hadronic radii. In this talk, we will give an overview of current and future TOTEM measurements together with theoretical explanation.
