One-loop divergences for KK theories on spaces; a reanalysis of ABJM precision holography
Federico Arrighi, Lorenzo Casarin
We provide a systematic framework for computing the logarithmically divergent part of one-loop partition functions on product spaces of arbitrar…
Semiclassical quantization of M5 brane probes wrapped on and defect anomalies
Matteo Beccaria, Lorenzo Casarin, Arkady A. Tseytlin
We consider two supersymmetric M5 brane probe solutions in and one in that all have the world-vo…
Conformal `anomalies' and renormalized stress-tensor correlators for non-conformal theories
Tommaso Bertolini, Lorenzo Casarin
We analyse the proposal of defining the Weyl anomaly for classically non-conformal theories as , originally put forwar…
Conformal anomalies for (maximal) 6d conformal supergravity
Lorenzo Casarin, Christian Kennedy, Gabriele Tartaglino-Mazzucchelli
We compute the conformal anomalies for 6d (2,0) conformal supergravity by direct calculation in component fields. The main novel results consist of the type-B anomaly coefficients…
Nicolai maps with four-fermion interactions
Lorenzo Casarin, Olaf Lechtenfeld, Maximilian Rupprecht
Nicolai maps offer an alternative description of supersymmetric theories via nonlinear and nonlocal transformations characterized by the so-called `free-action' and `determinant-ma…
Conformal anomalies in 6d 4-derivative theories: a heat-kernel analysis
Lorenzo Casarin
We compute the conformal anomalies for some higher-derivative (non-unitary) 6d Weyl invariant theories using the heat-kernel expansion in the background-field method. To this aim w…
ANEC on stress-tensor states in perturbative theory
Teresa Bautista, Lorenzo Casarin
We evaluate the Average Null Energy Condition (ANEC) on momentum eigenstates generated by the stress tensor in perturbative and general spacetime dimension. We first comp…
ANEC in theory
Teresa Bautista, Lorenzo Casarin, Hadi Godazgar
Motivated by the goal of applying the average null energy condition (ANEC) to renormalisation group flows, we calculate in theory the expectation value of the ANEC operator…
One-loop beta-functions in 4-derivative gauge theory in 6 dimensions
Lorenzo Casarin, Arkady A. Tseytlin
A classically scale-invariant 6d analog of the 4d Yang-Mills theory is the 4-derivative gauge theory with two independent couplings. Motivated by a search for…
Conformal Anomaly for Non-Conformal Scalar Fields
Lorenzo Casarin, Hadi Godazgar, Hermann Nicolai
We give a general definition of the conformal anomaly for theories that are not classically Weyl invariant and show that this definition yields a quantity that is both finite and l…
On higher-derivative gauge theories
Lorenzo Casarin
In this work we study the main properties and the one-loop renormalization of a Yang-Mills theory in which the kinetic term contains also a fourth-order differential operator; in p…
