Abstract
We present a brief overview of the physics potential of the Large Hadron Collider (LHC) and the role of quantum chromody- namics (QCD) in predicting various observables at the LHC with unprecedented accuracy. We have studied the production of Standard Model (SM) Higgs boson through gluon fusion channel and various signals of physics beyond the Standard Model (BSM) restricted to non-supersymmetric scenarios. These are models with large extra-dimensions such as ADD and Randall- Sundrum models and also physics senario resulting from scale/conformal invariant sector, namely unparticle physics. We have presented QCD effects to several of the observables in these models through higher order perturbative QCD corrections and parton distribution functions. We have demonstrated how the these corrections reduce the scale ambiguities coming from renormalisation and factorisation. Our study shows that the precise and unambiguous predictions are possible for various BSM studies at the LHC.
