    A test for emergent dynamics

    A generalization of a-maximization is proposed that maximizes a subject to inequalities rather than equalities. The implication of this conjecture is that in the absence of emergent symmetries, there is a maximum R-charge for fields appearing in the path integral. This maximum R-charge leads to a novel way of detecting emergent Abelian symmetries and non-Abelian gauge symmetries.Comment: 16 page

    Unbroken SU(2)SU(2) at a 100 TeV collider

    A future 100 TeV pp collider will explore energies much higher than the scale of electroweak (EW) symmetry breaking. In this paper we study some of the phenomenological consequences of this fact, concentrating on enhanced bremsstrahlung of EW gauge bosons. We survey a handful of possible new physics experimental searches one can pursue at a 100 TeV collider using this phenomenon. The most dramatic effect is the non-negligible radiation of EW gauge bosons from neutrinos, making them partly visible objects. The presence of collinear EW radiation allows for the full reconstruction of neutrinos under certain circumstances. We also show that the presence of EW radiation allows one to distinguish the SU(2)SU(2) quantum numbers of various new physics particles. We consider examples of two completely different new physics paradigms, additional gauge groups and SUSY, where the bremsstrahlung radiation of WW and ZZ from W′W's, Z′Z's or stops allows one to determine the couplings and the mixing angles of the new particles (respectively). Finally, we show how the emission of WWs and ZZs from high pTp_T Higgs bosons can be used to test the couplings of new physics to the Higgs boson.Comment: 27 pages, 10 figure
