Multiphoton signatures of goldstini at the LHC (2014)
Journal Article

We study models of gauge mediated SUSY breaking with more than one hidden sector. In these models the neutralino sector of the MSSM is supplemented with additional light neutral fermions, the nearly massless gravitino and the massive pseudo-goldstini...

Beyond effective field theory for dark matter searches at the LHC (2014)
Journal Article

We study the validity of effective field theory (EFT) interpretations of monojet searches for dark matter at the LHC for vector and axial-vector interactions. We show that the EFT approach is valid when the mediator has mass mmed greater than 2.5TeV.... Read More about Beyond effective field theory for dark matter searches at the LHC.

Collective coordinate approximation to the scattering of solitons in modified NLS and sine-Gordon models (2016)
Journal Article

We investigate the validity of collective coordinate approximations to the scattering of two solitons in several classes of (1+1) dimensional field theory models. We consider models which are deformations of the sine-Gordon (SG) or the nonlinear Schr¨...

Tripartite information of highly entangled states (2016)
Journal Article

Holographic systems require monogamous mutual information for validity of semiclassical geometry. This is encoded by the sign of the tripartite information (I3). We investigate the behaviour of I3 for all partitionings of systems in states which are... Read More about Tripartite information of highly entangled states.

The fluid manifesto: emergent symmetries, hydrodynamics, and black holes (2016)
Journal Article

We focus on the question of how relativistic fluid dynamics should be thought of as a Wilsonian effective field theory emerging from Schwinger-Keldysh path integrals. Taking the basic principles of Schwinger-Keldysh formalism seriously, we are led to... Read More about The fluid manifesto: emergent symmetries, hydrodynamics, and black holes.

A numerical routine for the crossed vertex diagram with a massive-particle loop (2019)
Journal Article

We present an evaluation of the two master integrals for the crossed vertex diagram with a closed loop of top quarks that allows for an easy numerical implementation. The differential equations obeyed by the master integrals are used to generate powe... Read More about A numerical routine for the crossed vertex diagram with a massive-particle loop.

Neutrino nonstandard interactions as a portal to test flavor symmetries (2019)
Journal Article

Imposing non-Abelian discrete flavor symmetries on neutrino nonstandard interactions (NSIs) is discussed for the first time. For definiteness, we choose A4 as the flavor symmetry, which is subsequently broken to the residual symmetry Z2 in the neutri... Read More about Neutrino nonstandard interactions as a portal to test flavor symmetries.

Holographic transport and density waves (2019)
Journal Article

We consider transport of heat and charge in holographic lattices which are phases of strongly coupled matter in which translations are broken explicitly. In these systems, we study a spontaneous density wave that breaks translations incommensurately... Read More about Holographic transport and density waves.

Generalized Gibbs ensemble and the statistics of KdV charges in 2D CFT (2019)
Journal Article

Two-dimensional CFTs have an infinite set of commuting conserved charges, known as the quantum KdV charges. We study the Generalized Gibbs Ensemble with chemical potentials for these charges at high temperature. In a large central charge limit, the p...

Modular A5 symmetry for flavour model building (2019)
Journal Article

In the framework of the modular symmetry approach to lepton flavour, we consider a class of theories where matter superfields transform in representations of the finite modular group Γ5 ≃ A5. We explicitly construct a basis for the 11 modular forms o... Read More about Modular A5 symmetry for flavour model building.

Neutrino masses from a dark neutrino sector below the electroweak scale (2019)
Journal Article

We consider a minimal extension of the Standard Model which advocates a dark neutrino sector charged under a hidden U(1)′. We show that neutrino masses can arise radiatively in this model. The observed values are compatible with a light dark sector b... Read More about Neutrino masses from a dark neutrino sector below the electroweak scale.

3d Abelian gauge theories at the boundary (2019)
Journal Article

A four-dimensional Abelian gauge field can be coupled to a 3d CFT with a U(1) symmetry living on a boundary. This coupling gives rise to a continuous family of boundary conformal field theories (BCFT) parametrized by the gauge coupling τ in the upper...

Leptogenesis via a varying Weinberg operator: a semi-classical approach (2019)
Journal Article

In this paper, we introduce leptogenesis via a varying Weinberg operator from a semi-classical perspective. This mechanism is motivated by the breaking of an underlying symmetry which triggers a phase transition that causes the coupling of the Weinbe...

Jet production in charged-current deep-inelastic scattering to third order in QCD (2019)
Journal Article

The production of jets in charged-current deep-inelastic scattering (CC DIS) probes simultaneously the strong and the electroweak sectors of the Standard Model; its measurement provides important information on the quark flavour structure of the prot...

Effective field theory of force-free electrodynamics (2019)
Journal Article

Force-free electrodynamics (FFE) is a closed set of equations for the electromagnetic field of a magnetically dominated plasma. There are strong arguments for the existence of force-free plasmas near pulsars and active black holes, but FFE alone cann... Read More about Effective field theory of force-free electrodynamics.

The one-loop amplitudes for Higgs + 4 partons with full mass effects (2020)
Journal Article

We present compact analytic formulae for the one-loop amplitudes for Higgs + 4 parton scattering, 0 → ggggh, 0 → qqggh ¯ and 0 → qq¯ q¯ 0 q 0h, mediated by a loop of massive coloured quarks. We exploit the correspondence with a theory in which a mass... Read More about The one-loop amplitudes for Higgs + 4 partons with full mass effects.

Searching for the odderon in ultraperipheral proton-ion collisions at the LHC (2019)
Journal Article

We explore the possibility of observing odderon exchange in proton-ion collisions at the LHC, via the ultraperipheral photoproduction of C-even mesons. As well as the signal, we consider in detail the principle backgrounds, due to QCD-initiated produ... Read More about Searching for the odderon in ultraperipheral proton-ion collisions at the LHC.

Gravitational wave and collider probes of a triplet Higgs sector with a low cutoff (2019)
Journal Article

We study the scalar triplet extension of the standard model with a low cutoff, preventing large corrections to the quadratic masses that would otherwise worsen the hierarchy problem. We explore the reach of LISA to test the parameter space region of... Read More about Gravitational wave and collider probes of a triplet Higgs sector with a low cutoff.
