New leading contributions to non-gaussianity in single field inflation

Ignatios Antoniadis, Auttakit Chatrabhuti, Jules Cunat, Hiroshi Isono

We compute the bispectrum of primordial density perturbations in CMB to second order in the slow-roll parameters of single field inflation. We found a large logarithmic contribution which is at least of the same order as the leading order result and can lead to an enhancement by an order of…

BPS Dendroscopy on Local $\mathbb{P}^1\times \mathbb{P}^1$

Bruno Le Floch, Boris Pioline, Rishi Raj

BPS states in type II string compactified on a Calabi-Yau threefold can typically be decomposed as moduli-dependent bound states of absolutely stable constituents, with a hierarchical structure labelled by attractor flow trees. This decomposition is best understood from the scattering diagram, an…

Simulating toponium formation signals at the LHC

Benjamin Fuks, Kaoru Hagiwara, Kai Ma, Ya-Juan Zheng

We present a method to simulate toponium formation events at the LHC using the Green's function of non-relativistic QCD in the Coulomb gauge, which governs the momentum distribution of top quarks in the presence of the QCD potential. This Green's function can be employed to re-weight any…

BRST Noether Theorem and Corner Charge Bracket

Laurent Baulieu, Tom Wetzstein, Siye Wu

We provide a proof of the BRST Noether 1.5th theorem, conjecture in [JHEP 10 (2024) 055], for a broad class of rank-1 BV theories including supergravity and 2-form gauge theories. The theorem asserts that the BRST Noether current of any BRST invariant gauge fixed Lagrangian decomposes on-shell into…
