This book mainly investigates the precision predictions on the signal of
new physics at the Large Hadron Collider (LHC) in the perturbative
Quantum Chromodynamics (QCD) scheme. The potential of the LHC to
discover the signal of dark matter associated production with a photon
is studied after including next-to-leading order QCD corrections. The
factorization and resummation of t-channel top quark transverse momentum
distribution in the standard model at both the Tevatron and the LHC with
soft-collinear effective theory are presented. The potential of the
early LHC to discover the signal of monotops is discussed. These
examples illustrate the method of searching for new physics beyond what
is known today with high precision.
