Fermion-Monopole Scattering in the Standard Model
Marieke van Beest, Philip Boyle Smith, Diego Delmastro +2
We study the scattering of fermions off 't Hooft lines in the Standard Model. A long-standing paradox suggests that the outgoing fermions necessarily carry fractional quantum numbe…
Monopoles, Scattering, and Generalized Symmetries
Marieke van Beest, Philip Boyle Smith, Diego Delmastro +2
We reconsider the problem of electrically charged, massless fermions scattering off magnetic monopoles. The interpretation of the outgoing states has long been a puzzle as, in cert…
Classification of chiral fermionic CFTs of central charge
Philip Boyle Smith, Ying-Hsuan Lin, Yuji Tachikawa +1
We classify two-dimensional purely chiral conformal field theories which are defined on two-dimensional surfaces equipped with spin structure and have central charge less than or e…
On Discrete Anomalies in Chiral Gauge Theories
Philip Boyle Smith, Avner Karasik, Nakarin Lohitsiri +1
We study two well-known chiral gauge theories with fermions in the symmetric, anti-symmetric and fundamental representations. We give a detailed description of the global s…
Boundary States and Anomalous Symmetries of Fermionic Minimal Models
Philip Boyle Smith
The fermionic minimal models are a recently-introduced family of two-dimensional spin conformal field theories. We determine all of their conformal boundary states and potentially…
What Symmetries are Preserved by a Fermion Boundary State?
Philip Boyle Smith, David Tong
Usually, a left-moving fermion in d=1+1 dimensions reflects off a boundary to become a right-moving fermion. This means that, while overall fermion parity is conserved, ch…
