Consistent Scattering Amplitudes, Yang-Mills, the Higgs Mechanism and the EFTs Beyond
Timothy Trott
I study constraints on fundamental physics emerging from consistency of a unitary, local and perturbative -matrix in . For massless particles, some new constraints arising f…
Solutions to Problems at Les Houches Summer School on EFT
Marcel Balsiger, Marios Bounakis, Mehdi Drissi +10
This work details worked solutions to the various problems set by the lecturers during the course of the Les Houches summer school 2017 on effective field theories in particle phys…
Cosmological Signals of a Mirror Twin Higgs
Nathaniel Craig, Seth Koren, Timothy Trott
We investigate the cosmology of the minimal model of neutral naturalness, the mirror Twin Higgs. The softly-broken mirror symmetry relating the Standard Model to its twin counterpa…
Massive On-Shell Supersymmetric Scattering Amplitudes
Aidan Herderschee, Seth Koren, Timothy Trott
We introduce a manifestly little group covariant on-shell superspace for massive particles in four dimensions using the massive spinor helicity formalism. This enables us to constr…
The Muon Smasher's Guide
Hind Al Ali, Nima Arkani-Hamed, Ian Banta +31
We lay out a comprehensive physics case for a future high-energy muon collider, exploring a range of collision energies (from 1 to 100 TeV) and luminosities. We highlight the advan…
Causality, Unitarity and Symmetry in Effective Field Theory
Timothy Trott
Sum rules in effective field theories, predicated upon causality, place restrictions on scattering amplitudes mediated by effective contact interactions. Through unitarity of the $…
Supersymmetry, Supergravity and the Consistency of On-Shell Massive Superamplitudes
Timothy Trott
I study constraints from consistent complex factorisation of scattering amplitudes in and their relationship with supersymmetry. I complete the argument demon…
Constructing Coulomb Branch Superamplitudes
Aidan Herderschee, Seth Koren, Timothy Trott
We study scattering amplitudes of massive BPS states on the Coulomb branch of super-Yang-Mills, utilising a little group covariant on-shell superspace for mass…
SUSY Implications from WIMP Annihilation into Scalars at the Galactic Centre
Tony Gherghetta, Benedict von Harling, Anibal D. Medina +2
An excess in gamma-rays emanating from the galactic centre has recently been observed in the Fermi-LAT data. This signal can be interpreted as resulting from WIMP annihilation, wit…
