Determination of HQET nonperturbative matrix elements with renormalon subtraction using Fourier transform [PDF]
EPJ Web of Conferences, 2022 As higher order perturbative series are available, it is becoming necessary to include nonperturbative effects in QCD calculations using the OPE. In order to systematically determine nonperturbative effects and to incorporate them into theoretical ...

Scattering amplitudes and electromagnetic horizons
Journal of High Energy Physics, 2023 We consider the scattering of charged particles on particular electromagnetic fields which have properties analogous to gravitational horizons. Classically, particles become causally excluded from regions of spacetime beyond a null surface which we ...

CFT description of BH’s and ECO’s: QNMs, superradiance, echoes and tidal responses
Journal of High Energy Physics, 2022 Using conformal field theory and localization tecniques we study the propagation of scalar waves in gravity backgrounds described by Schrödinger like equations with Fuchsian singularities.

Critical behavior of the 2d scalar theory: resumming the N8LO perturbative mass gap
Journal of High Energy Physics, 2021 We apply the optimized perturbation theory (OPT) to resum the perturbative series describing the mass gap of the bidimensional ϕ 4 theory in the ℤ2 symmetric phase.

Emergent symmetry in Brownian SYK models and charge dependent scrambling
Journal of High Energy Physics, 2022 In this work, we introduce a symmetry-based approach to study the scrambling and operator dynamics of Brownian SYK models at large finite N and in the infinite N limit.

Scattering amplitudes from dispersive iterations of unitarity
Journal of High Energy Physics, 2023 We present and numerically implement a computational method to construct relativistic scattering amplitudes that obey analyticity, crossing, elastic and inelastic unitarity in three and four spacetime dimensions.

Drell-Yan angular lepton distributions at small x from TMD factorization.
Journal of High Energy Physics, 2021 The Drell-Yan process is studied in the framework of TMD factorization in the Sudakov region s » Q 2 » q ⊥ 2 $$ {q}_{\perp}^2 $$ corresponding to recent LHC experiments with Q 2 of order of mass of Z-boson and transverse momentum of DY pair ∼ few tens ...

Tunnelling of charged particles from black holes
Journal of High Energy Physics, 2020 We state and explain the total rate at which a charged non-rotating black hole emits charged particles, taking into account both Hawking radiation and Schwinger pair production simultaneously.

The axion quality problem: global symmetry breaking and wormholes
Journal of High Energy Physics, 2021 Continuous global symmetries are expected to be broken by gravity, which can lead to important phenomenological consequences. A prime example is the threat that this poses to the viability of the Peccei-Quinn solution to the strong CP problem.

Journal of High Energy Physics, 2021 We study neutral fermions pair creation with anomalous magnetic moment from the vacuum by time-independent magnetic-field inhomogeneity as an external background. We show that the problem is technically reduced to the problem of charged-particle creation
