Elastic proton-proton scattering at 13 TeV (2018)
Journal Article

The predictions of a model which was tuned in 2013 to describe the elastic and diffractive p p - and/or p ¯ p -data at collider energies up to 7 TeV are compared with the new 13 TeV TOTEM results. The possibility of the presence of an odd-signature O... Read More about Elastic proton-proton scattering at 13 TeV.

Entanglement entropy in three dimensional gravity (2015)
Journal Article

The Ryu-Takayanagi (RT) and covariant Hubeny-Rangamani-Takayanagi (HRT) proposals relate entanglement entropy in CFTs with holographic duals to the areas of minimal or extremal surfaces in the bulk geometry. We show how, in three dimensional pure gra... Read More about Entanglement entropy in three dimensional gravity.

Anatomy of the amplituhedron (2015)
Journal Article

We initiate a comprehensive investigation of the geometry of the amplituhedron, a recently found geometric object whose volume calculates the integrand of scattering amplitudes in planar N = 4 SYM theory. We do so by introducing and studying its stra... Read More about Anatomy of the amplituhedron.

On axion monodromy inflation in warped throats (2015)
Journal Article

Recent models of axion monodromy inflation in string theory link the inflationary potential and the moduli stabilization potential. Realistic inflationary models require mechanisms to moderately suppress the inflaton mass with respect to the moduli s... Read More about On axion monodromy inflation in warped throats.

Topological sigma models & dissipative hydrodynamics (2016)
Journal Article

We outline a universal Schwinger-Keldysh effective theory which describes macroscopic thermal fluctuations of a relativistic field theory. The basic ingredients of our construction are three: a doubling of degrees of freedom, an emergent abelian symmetr... Read More about Topological sigma models & dissipative hydrodynamics.

Boomerang RG flows with intermediate conformal invariance (2018)
Journal Article

For a class of D = 5 holographic models we construct boomerang RG flow solutions that start in the UV at an AdS5 vacuum and end up at the same vacuum in the IR. The RG flows are driven by deformations by relevant operators that explicitly break trans... Read More about Boomerang RG flows with intermediate conformal invariance.

Anomalous coupling, top-mass and parton-shower effects in W + W − production (2016)
Journal Article

We calculate the process pp → W+W− → e+νeµ−¯ νµ at NLO QCD, including also effective field theory (EFT) operators mediating the ggW+W− interaction, which first occur at dimension eight. We further combine the NLO and EFT matrix elements produced by GoSa... Read More about Anomalous coupling, top-mass and parton-shower effects in W + W − production.

Black disk, maximal Odderon and unitarity (2018)
Journal Article

We argue that the so-called maximal Odderon contribution breaks the ‘black disk’ behaviorof the asymp-totic amplitude, since the cross section of the events with Large Rapidity Gaps grows faster than the total cross section. That is the ‘maximal Odde... Read More about Black disk, maximal Odderon and unitarity.

Gravity waves on modulated flows downstream from an obstacle: The transcritical case (2018)
Journal Article

Periodic spatial modulations arise in analogue gravity experiments aimed at detecting the analogue version of the Hawking effect in a white-hole flow. Having the same spatial periodicity as low-frequency dispersive modes, they can induce resonances w...

Decoding perturbation theory using resurgence: Stokes phenomena, new saddle points and Lefschetz thimbles (2015)
Journal Article

Resurgence theory implies that the non-perturbative (NP) and perturbative (P) data in a QFT are quantitatively related, and that detailed information about non-perturbative saddle point field configurations of path integrals can be extracted from per...

Charming new physics in rare B decays and mixing? (2018)
Journal Article

We conduct a systematic study of the impact of new physics in quark-level b → ccs¯ transitions on B physics, in particular rare B decays and B-meson lifetime observables. We find viable scenarios where a sizable effect in rare semileptonic B decays c... Read More about Charming new physics in rare B decays and mixing?.

Analytic result for the nonplanar hexa-box integrals (2019)
Journal Article

In this paper, we analytically compute all master integrals for one of the two non-planar integral families for five-particle massless scattering at two loops. We first derive an integral basis of 73 integrals with constant leading singularities. We... Read More about Analytic result for the nonplanar hexa-box integrals.

The impact of LHC jet data on the MMHT PDF fit at NNLO (2018)
Journal Article

We investigate the impact of the high precision ATLAS and CMS 7 TeV measurements of inclusive jet production on the MMHT global PDF analysis at next-to-next-to-leading order (NNLO). This is made possible by the recent completion of the long-term proj... Read More about The impact of LHC jet data on the MMHT PDF fit at NNLO.

Single top-quark production with sherpa (2018)
Journal Article

We present results at next-to-leading order accuracy in QCD for single top-quark production in the t, s and tW channels at the lhc at a centre-of-mass energy of 8TeV, obtained with the sherpa event generator. We find them in very good agreement with... Read More about Single top-quark production with sherpa.

3d N=4 Super-Yang-Mills on a Lattice (2018)
Journal Article

In this paper we explore a new approach to studying three-dimensional N=4 super-Yang-Mills on a lattice. Our strategy is to complexify the Donaldson-Witten twist of four-dimensional N=2 super-Yang-Mills to make it amenable to a lattice formulation an...

Emergent dark gravity from (non)holographic screens (2019)
Journal Article

In this work, a clear connection is made between E. Verlinde’s recent theory of emergent gravity in de Sitter space, and the earlier work describing emergent gravity using holographic screens. A modified (non)holographic screen scenario is presented,... Read More about Emergent dark gravity from (non)holographic screens.

Diffusion for holographic lattices (2018)
Journal Article

We consider black hole spacetimes that are holographically dual to strongly coupled field theories in which spatial translations are broken explicitly. We discuss how the quasinormal modes associated with diffusion of heat and charge can be systemati... Read More about Diffusion for holographic lattices.

Dynamics of linked filaments in excitable media (2019)
Journal Article

In this paper we present the results of parallel numerical computations of the long-term dynamics of linked vortex filaments in a three-dimensional FitzHugh–Nagumo excitable medium. In particular, we study all torus links with no more than 12 crossin... Read More about Dynamics of linked filaments in excitable media.
