Journal of High Energy Physics, 2021 We compute ε-expansions around 4 dimensions of a complete set of master integrals for momentum space five-loop massless propagator integrals in dimensional regularization, up to and including the first order with contributions of transcendental weight ...

Formulation for renormalon-free perturbative predictions beyond large-β 0 approximation
Journal of High Energy Physics, 2020 We present a formulation to give renormalon-free predictions consistently with fixed order perturbative results. The formulation has a similarity to Lee’s method in that the renormalon-free part consists of two parts: one is given by a series expansion ...

Journal of High Energy Physics, 2021 Building on the recent derivation of a bare factorization theorem for the b-quark induced contribution to the h → γγ decay amplitude based on soft-collinear effective theory, we derive the first renormalized factorization theorem for a process described ...

Journal of High Energy Physics, 2019 For a general N $$ \mathcal{N} $$ = 1 supersymmetric gauge theory regularized by higher covariant derivatives we prove in all orders that the β-function defined in terms of the bare couplings is given by integrals of double total derivatives with respect

Qubits on the horizon: decoherence and thermalization near black holes
Journal of High Energy Physics, 2021 We examine the late-time evolution of a qubit (or Unruh-De Witt detector) that hovers very near to the event horizon of a Schwarzschild black hole, while interacting with a free quantum scalar field.

Journal of High Energy Physics, 2018 We investigate a recently proposed new form of the exact NSVZ β-function, which relates the β-function to the anomalous dimensions of the quantum gauge superfield, of the Faddeev-Popov ghosts, and of the chiral matter superfields. Namely, for the general

Journal of High Energy Physics, 2021 Effective theories describing black hole exteriors contain many open-system features due to the large number of gapless degrees of freedom that lie beyond reach across the horizon.

Journal of High Energy Physics, 2020 The contributions of the matter superfields and of the Faddeev-Popov ghosts to the β-function of N $$ \mathcal{N} $$ = 1 supersymmetric gauge theories defined in terms of the bare couplings are calculated in all orders in the case of using the higher ...

Analytic resurgence in the O(4) model
Journal of High Energy Physics, 2022 We study the perturbative expansion of the ground state energy in the presence of an external field coupled to a conserved charge in the integrable two-dimensional O(4) nonlinear sigma model.

Journal of High Energy Physics, 2019 The three-loop Adler D-function for N = 1 $$ \mathcal{N}=1 $$ SQCD in the D R ¯ $$ \overline{\mathrm{DR}} $$ scheme is calculated starting from the three-loop result recently obtained with the higher covariant derivative regularization. For this purpose,
