EFT of 6D SUSY RG Flows
Jonathan J. Heckman, Sandipan Kundu, Hao Y. Zhang
Motivated by its potential use in constraining the structure of 6D renormalization group flows, we determine the low energy dilaton-axion effective field theory of conformal and gl…
Causality Constraints in Large QCD Coupled to Gravity
Jared Kaplan, Sandipan Kundu
Confining gauge theories contain glueballs and mesons with arbitrary spin, and these particles become metastable at large . However, metastable higher spin particles, when coupl…
Closed Strings and Weak Gravity from Higher-Spin Causality
Jared Kaplan, Sandipan Kundu
We combine old and new quantum field theoretic arguments to show that any theory of stable or metastable higher spin particles can be coupled to gravity only when the gravity secto…
A Generalized Nachtmann Theorem in CFT
Sandipan Kundu
Correlators of unitary quantum field theories in Lorentzian signature obey certain analyticity and positivity properties. For interacting unitary CFTs in more than two dimensions,…
Renormalization Group Flows, the -Theorem and Conformal Bootstrap
Sandipan Kundu
Every renormalization group flow in spacetime dimensions can be equivalently described as spectral deformations of a generalized free CFT in spacetime dimensions. This…
A Species or Weak-Gravity Bound for Large Gauge Theories Coupled to Gravity
Jared Kaplan, Sandipan Kundu
Causality constrains the gravitational interactions of massive higher spin particles in both AdS and flat spacetime. We explore the extent to which these constraints apply to compo…
