Effective Field Theories for the LHC | | Ian Moult

Mon, 2 May 2016 17:27:33 GMT (11860kb,D) | | Abstract: | In this thesis I study applications of effective field theories to understand
aspects of QCD jets and their substructure at the Large Hadron Collider. In
particular, I introduce an observable, $D_2$, which can be used for
distinguishing boosted $W/Z/H$ bosons from the QCD background using information
about the radiation pattern within the jet, and perform a precision calculation
of this observable. To simplify calculations in the soft collinear effective
theory, I also develop a helicity operator basis, which facilitates matching
calculations to fixed order computations performed using spinor-helicity
techniques, and demonstrate its utility by computing an observable relevant for
studying the properties of the newly discovered Higgs boson. | | Source: | arXiv, 1605.0573 | | Services: | Forum | Review | PDF | Favorites | |
