Chirality Changing RG Flows: Dynamics and Models
Yuri Shirman, Shreya Shukla, Michael Waterbury
Chirality plays an important role in understanding the dynamics of quantum field theories. In this paper, we study the dynamics of models where renormalization group flows change t…
Generation flow in field theory and strings
Saul Ramos-Sanchez, Michael Ratz, Yuri Shirman +2
Nontrivial strong dynamics often leads to the appearance of chiral composites. In phenomenological applications, these can either play the role of Standard Model particles or lift…
Monopoles Entangle Fermions
Csaba Csáki, Yuri Shirman, Ofri Telem +1
We resolve the decades old mystery of what happens when a positron scatters off a minimal GUT monopole in an s-wave, first discussed by Callan in 1983. Using the language of on-she…
Multi-particle Representations of the Poincaré Group
Csaba Csáki, Sungwoo Hong, Yuri Shirman +2
In this work we extend the definition of asymptotic multi-particle states of the -matrix, beyond the direct products of one-particle states. We identify new quantum numbers whic…
Scattering Amplitudes for Monopoles: Pairwise Little Group and Pairwise Helicity
Csaba Csaki, Sungwoo Hong, Yuri Shirman +3
On-shell methods are particularly suited for exploring the scattering of electrically and magnetically charged objects, for which there is no local and Lorentz invariant Lagrangian…
The Axion Mass from 5D Small Instantons
Tony Gherghetta, Valentin V. Khoze, Alex Pomarol +1
We calculate a new contribution to the axion mass that arises from gluons propagating in a 5th dimension at high energies. By uplifting the 4D instanton solution to five dimensions…
