Neutrino masses from generalized symmetry breaking

C Cordova, S Hong, S Koren, K Ohmori - Physical Review X, 2024 - APS
We explore generalized global symmetries in theories of physics beyond the standard
model. Theories of Z′ bosons generically contain “noninvertible” chiral symmetries, whose …

Coupling a Cosmic String to a TQFT

TD Brennan, S Hong, LT Wang - Journal of High Energy Physics, 2024 - Springer
A bstract A common framework of particle physics consists of two sectors of particles, such
as the Standard Model and a dark sector, with some interaction between them. In this work …

Line defect quantum numbers & anomalies

TD Brennan, C Cordova, TT Dumitrescu - arxiv preprint arxiv:2206.15401, 2022 - arxiv.org
We explore the connection between the global symmetry quantum numbers of line defects
and't Hooft anomalies. Relative to local (point) operators, line defects may transform …

Higher flavor symmetries in the Standard Model

C Córdova, S Koren - Annalen der Physik, 2023 - Wiley Online Library
A study of the generalized global flavor symmetries of the Standard Model is initiated. The
presence of nonzero triangle diagrams between the U (3) 5 flavor currents and the U (1) …

The gaugino condensate from asymmetric four-torus with twists

MM Anber, E Poppitz - Journal of High Energy Physics, 2023 - Springer
A bstract We calculate the gaugino condensate in SU (2) super Yang-Mills theory on an
asymmetric four-torus 𝕋 4 with't Hooft's twisted boundary conditions. The 𝕋 4 asymmetry is …

Semiclassics with't Hooft flux background for QCD with 2-index quarks

Y Tanizaki, M Ünsal - Journal of High Energy Physics, 2022 - Springer
A bstract We study quantum chromodynamics including the two-index symmetric or anti-
symmetric quark (QCD (Sym/ASym)) on small ℝ 2× T 2 with a suitable magnetic flux. We first …

2-index chiral gauge theories

MM Anber, SYL Chan - Journal of High Energy Physics, 2023 - Springer
A bstract We undertake a systematic study of the 4-dimensional SU (N) 2-index chiral gauge
theories and investigate their faithful global symmetries and dynamics. These are a finite set …

Noninvertible anomalies in SU (N)× U (1) gauge theories

MM Anber, E Poppitz - Journal of High Energy Physics, 2023 - Springer
A bstract We study 4-dimensional SU (N)× U (1) gauge theories with a single massless Dirac
fermion in the 2-index symmetric/antisymmetric representations and show that they are …
