Black holes, white holes, and near-horizon physics
Journal of High Energy PhysicsBlack and white holes play remarkably contrasting roles in general relativity versus observational astrophysics. While there is observational evidence for the existence of compact objects that are “cold, dark, and heavy”, which thereby are natural ...

Holographic complexity of the extended Schwarzschild-de Sitter space
Journal of High Energy PhysicsAccording to static patch holography, de Sitter space admits a unitary quantum description in terms of a dual theory living on the stretched horizon, that is a timelike surface close to the cosmological horizon.

Testing the scalar weak gravity conjecture in no-scale supergravity
Journal of High Energy PhysicsWe explore possible extensions of the Weak Gravity Conjecture (WGC) to scalar field theories. To avoid charged black hole remnants, the WGC requires the existence of a particle with a mass m ≤ gqM P , with charge q and U(1) gauge coupling g, allowing the

Renormalization of the next-to-leading-power γγ → h and gg → h soft quark functions
Journal of High Energy PhysicsWe calculate directly in position space the one-loop renormalization kernels of the soft operators O γ and O g that appear in the soft-quark contributions to, respectively, the subleading-power γγ → h and gg → h form factors mediated by the b-quark.

Peccei-Quinn inflation at the pole and axion kinetic misalignment
Journal of High Energy PhysicsWe propose a minimal extension of the Standard Model with the Peccei-Quinn (PQ) scalar field and explain the relic density of the QCD axion through the kinetic misalignment with a relatively small axion decay constant. To this purpose, we consider a slow-

Gauge field fluctuation corrected QED3 effective action by fermionic particle-vortex duality
Journal of High Energy PhysicsWe present a non-perturbative framework for incorporating gauge field fluctuations into effective actions of QED3 in the infrared using fermionic particle-vortex duality.

Regge growth of isolated massive spin-2 particles and the Swampland
Journal of High Energy PhysicsWe 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 ...

Journal of High Energy PhysicsIn 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 PhysicsRecently, 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 PhysicsIntegrability 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.
