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 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 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 and from s, 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 s and s from high Higgs bosons can be used to test
the couplings of new physics to the Higgs boson.Comment: 27 pages, 10 figure
