The fermion sector of the SMEFT from asymptotically safe gravity
Astrid Eichhorn, Moritz Gessner, Shouryya Ray
Quantum gravity impacts Standard Model fields through effective interactions generated by renormalization. These appear as Standard Model Effective Field Theory (SMEFT) operators,…
Non-Lagrangian phases of matter from Wilsonian renormalization of 3D Wess-Zumino-Witten theory on Stiefel manifolds
Shouryya Ray
I study the renormalization of D-dimensional level-k Wess-Zumino-Witten theory with Stiefel-manifold target space , wit…
Gross-Neveu-Yukawa SO(2) and SO(3) tensorial criticality
SangEun Han, Shouryya Ray, Igor F. Herbut
We investigate the relativistic SO(2)- and SO(3)-invariant Gross-Neveu-Yukawa field theories for real, rank-two, symmetric, traceless tensor order parameters coupled to $N_{\text{f…
A non-local way around the no-global-symmetries conjecture in quantum gravity?
Johanna Borissova, Astrid Eichhorn, Shouryya Ray
The no-global-symmetries conjecture is central to the swampland program that delineates the boundary between effective field theories that can be obtained from a quantum theory of…
