Multidimensional effective field theory analysis for direct detection of dark matter (2017)
Journal Article

The scattering of dark matter particles off nuclei in direct detection experiments can be described in terms of a multidimensional effective field theory (EFT). A new systematic analysis technique is developed using the EFT approach and Bayesian infe... Read More about Multidimensional effective field theory analysis for direct detection of dark matter.

Dark matter-neutrino interactions through the lens of their cosmological implications (2018)
Journal Article

Dark matter and neutrinos provide the two most compelling pieces of evidence for new physics beyond the Standard Model of particle physics, but they are often treated as two different sectors. The aim of this paper is to determine whether there are v... Read More about Dark matter-neutrino interactions through the lens of their cosmological implications.

Reopening the Higgs portal for single scalar dark matter (2017)
Journal Article

A real singlet scalar, connected to the Standard Model sector through a portal with the Higgs boson, is one of the simplest and most popular models for dark matter (DM). However, the experimental advances in direct and indirect DM searches, together... Read More about Reopening the Higgs portal for single scalar dark matter.

The triple Higgs coupling: a new probe of low-scale seesaw models (2017)
Journal Article

The measure of the triple Higgs coupling is one of the major goals of the high-luminosity run of the CERN Large Hadron Collider (HL-LHC) as well as the future colliders, either leptonic such as the International Linear Collider (ILC) or hadronic such...

Renormalization-group equations of neutrino masses and flavor mixing parameters in matter (2018)
Journal Article

We borrow the general idea of renormalization-group equations (RGEs) to understand how neutrino masses and flavor mixing parameters evolve when neutrinos propagate in a medium, highlighting a meaningful possibility that the genuine flavor quantities...

Uncertainties on αSαS in the MMHT2014 global PDF analysis and implications for SM predictions (2015)
Journal Article

We investigate the uncertainty in the strong coupling αS(M2Z)αS(MZ2) when allowing it to be a free parameter in the recent MMHT global analyses of deep-inelastic and related hard scattering data that was undertaken to determine the parton distributio...

Advantages of exclusiveγγproduction to probe high mass systems (2016)
Journal Article

We recall that the exclusive production of high mass objects via γγ fusion at the LHC is not strongly suppressed in comparison with inclusive γγ fusion. Therefore it may be promising to study new objects, X, produced by the γγ subprocess in experimen... Read More about Advantages of exclusiveγγproduction to probe high mass systems.

Exclusive J=ψ production at the LHC in the kT factorisation approach (2017)
Journal Article

The recent LHCb data for exclusive J y peripheral production at 13 TeV motivate an improved ‘NLO’ analysis to estimate the gluon distribution at low x in which we re-calculate the rapidity gap survival factors and use a more precise expression for th...

B+L violation at colliders and new physics (2018)
Journal Article

Chiral electroweak anomalies predict baryon (B) and lepton (L) violating fermion interactions, which can be dressed with large numbers of Higgs and gauge bosons. The estimation of the total B + L-violating rate from an initial two-particle state — po... Read More about B+L violation at colliders and new physics.

Instanton operators and the Higgs branch at infinite coupling (2017)
Journal Article

The richness of 5d N=1N=1 theories with a UV fixed point at infinite coupling is due to the existence of local disorder operators known as instanton operators. By considering the Higgs branch of SU(2) gauge theories with Nf ≤ 7 flavours at finite and... Read More about Instanton operators and the Higgs branch at infinite coupling.

Boundary scattering in the ϕ4 model (2017)
Journal Article

We study boundary scattering in the ϕ4 model on a half-line with a oneparameter family of Neumann-type boundary conditions. A rich variety of phenomena is observed, which extends previously-studied behaviour on the full line to include regimes of nea... Read More about Boundary scattering in the ϕ4 model.

A Bound on the Pseudospectrum for a Class of Non-normal Schrödinger Operators (2016)
Journal Article

We are concerned with the non-normal Schrödinger operator H=−Δ+VH=−Δ+V on L2(Rn)L2(Rn) , where V∈W1,∞loc(Rn)V∈Wloc1,∞(Rn) and ReV(x)≥c∣x∣2−dReV(x)≥c∣x∣2−d for some c,d>0c,d>0 . The spectrum of this operator is discrete and its real part is bounded be... Read More about A Bound on the Pseudospectrum for a Class of Non-normal Schrödinger Operators.

Divergences in Holographic Complexity (2017)
Journal Article

We study the UV divergences in the action of the 'Wheeler-de Witt patch' in asymptotically AdS spacetimes, which has been conjectured to be dual to the computational complexity of the state of the dual field theory on a spatial slice of the boundary....

Addressing neutrino mixing models with DUNE and T2HK (2018)
Journal Article

We consider schemes of neutrino mixing arising within the discrete symmetry approach to the well-known flavour problem. We concentrate on 3ν mixing schemes in which the cosine of the Dirac CP violation phase δCP satisfies a sum rule by which it is ex...

Tensor network models of multiboundary wormholes (2017)
Journal Article

We study the entanglement structure of states dual to multiboundary wormhole geometries using tensor network models. Perfect and random tensor networks tiling the hyperbolic plane have been shown to provide good models of the entanglement structure i...

A new smooth-k space filter approach to calculate halo abundances (2018)
Journal Article

We propose a new filter, a smooth-k space filter, to use in the Press-Schechter approach to model the dark matter halo mass function which overcomes shortcomings of other filters. We test this against the mass function measured in N-body simulations.... Read More about A new smooth-k space filter approach to calculate halo abundances.

Top quark mass studies with tt¯j at the LHC (2018)
Journal Article

A precise measurement of the top quark mass, a fundamental parameter of the Standard Model, is among the most important goals of top quark studies at the Large Hadron Collider. Apart from the standard methods, numerous new observables and reconstruct... Read More about Top quark mass studies with tt¯j at the LHC.

Resurgence of the dressing phase for AdS5 × S5 (2017)
Journal Article

We discuss the resummation of the strong coupling asymptotic expansion of the dressing phase of the AdS5 × S5 superstring. The dressing phase proposed by Beisert, Eden and Staudacher can be recovered from a modified Borel-Ecalle resummation of this a... Read More about Resurgence of the dressing phase for AdS5 × S5.

Next-to-Next-to-Leading-Order QCD Corrections to the Transverse Momentum Distribution of Weak Gauge Bosons (2018)
Journal Article

The transverse momentum spectra of weak gauge bosons and their ratios probe the underlying dynamics and are crucial in testing our understanding of the standard model. They are an essential ingredient in precision measurements, such as the W boson ma...

Simulating b-associated production of Z and Higgs bosons with the SHERPA event generator (2017)
Journal Article

We compare four- and five-flavor scheme predictions for b-associated production of Z and Higgs bosons. The results are obtained with SHERPA ’s MC@NLO implementation for the four-flavor scheme, treating the b’s as massive, and with multijet merging at...
