Regge growth of isolated massive spin-2 particles and the Swampland

Journal of High Energy Physics
We consider an effective theory with a single massive spin-2 particle and a gap to the cutoff. We couple the spin-2 particle to gravity, and to other lower-spin fields, and study the growth of scattering amplitudes of the particle in the Regge regime ...

Interacting chiral form field theories and T T ¯ $$ T\overline{T} $$ -like flows in six and higher dimensions

Journal of High Energy Physics
In this paper we initiate the study of six-dimensional non-linear chiral two-form gauge theories as deformations of free chiral two-form gauge theories driven by stress-tensor T T ¯ $$ T\overline{T} $$ -like flows.

Electroweak three-body decays in the presence of two- and three-body bound states

Journal of High Energy Physics
Recently, formalism has been derived for studying electroweak transition amplitudes for three-body systems both in infinite and finite volumes. The formalism provides exact relations that the infinite-volume amplitudes must satisfy, as well as a ...

Fast QSC solver: tool for systematic study of N $$ \mathcal{N} $$ = 4 Super-Yang-Mills spectrum

Journal of High Energy Physics
Integrability methods give us access to a number of observables in the planar N $$ \mathcal{N} $$ = 4 SYM. Among them, the Quantum Spectral Curve (QSC) governs the spectrum of anomalous dimensions.

Phenomenology of a Deconstructed Electroweak Force

Journal of High Energy Physics
We study an effective theory of flavour in which the SU(2) L interaction is ‘flavour-deconstructed’ near the TeV scale. This arises, for example, in UV models that unify all three generations of left-handed fermions via an Sp(6) L symmetry.

Effects on neutrino propagation in space-time foam of D-branes revisited

Journal of High Energy Physics
Neutrinos from the cosmos have proven to be ideal for probing the nature of space-time. Previous studies on high-energy events of IceCube suggested that some of these events might be gamma-ray burst neutrinos, with their speeds varying linearly with ...

Superconformal indices and localization in N = 2B quantum mechanics

Journal of High Energy Physics
Superconformal ‘type B’ quantum mechanical sigma models arise in a variety of interesting contexts, such as the description of D-brane bound states in an AdS2 decoupling limit.

Generalized covariant entropy bound in Einstein gravity with quadratic curvature corrections

Journal of High Energy Physics
We explore the generalized covariant entropy bound in the theory where Einstein gravity is perturbed by quadratic curvature terms, which can be viewed as the first-order quantum correction to Einstein gravity.

Einstein gravity with generalized cosmological term from five-dimensional AdS-Maxwell-Chern-Simons gravity

Journal of High Energy Physics
Some time ago, the standard geometric framework of Einstein gravity was extended by gauging the Maxwell algebra as well as the so called AdS-Maxwell algebra.

Minimal flavour deconstruction

Journal of High Energy Physics
We construct two concrete examples of flavour non-universal gauge theories which, after the inclusion of all d ≤ 4 gauge invariant operators, allow to describe the observed pattern of flavour in the charged fermion sector without any small Yukawa ...
