Title: Identifying physics Beyond the Standard Model at the LHC
Host: Luty
Room: 432
Many BSM theories predict new heavy particle states that are
identical to their SM counterparts but are heavier. In SUSY, the
superpartners differ in spin by a half-integer from their SM counterparts,
whereas Kaluza-Klein resonances have the same spin as the SM zero modes.
Measuring spin thus provides a crucial handle on distinguishing new physics
models at the LHC. The first part of this talk is about spin measurement of
new particles at the LHC using the azimuthal angular distribution of decay
products from a parent particle whose spin we wish to measure. This
technique is model independent and relies only on simple angular momentum
rules and quantum mechanics. In the second part of the talk we discuss WZ
scattering at the LHC. We find that the same azimuthal angle can be used as
a probe of a strongly coupled Higgs sector.
