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.Springer Theses, Recognizing Outstanding Ph.D. Research,2190-5053Elementary particles (Physics)Quantum field theoryString theoryElementary Particles, Quantum Field Theoryhttps://scigraph.springernature.com/ontologies/product-market-codes/P23029Quantum Field Theories, String Theoryhttps://scigraph.springernature.com/ontologies/product-market-codes/P19048Elementary particles (Physics).Quantum field theory.String theory.Elementary Particles, Quantum Field Theory.Quantum Field Theories, String Theory.539.7548Wang Jianauthttp://id.loc.gov/vocabulary/relators/aut525063MiAaPQMiAaPQMiAaPQBOOK9910254612003321QCD Higher-Order Effects and Search for New Physics2528319UNINA
