Resummed Higgs cross section at N3LL (2014)
Journal Article

We present accurate predictions for the inclusive production of a Higgs boson in proton-proton collisions, via gluon-gluon fusion. Our calculation includes nextto-next-to-leading order (NNLO) corrections in perturbative QCD, as well as the resummatio... Read More about Resummed Higgs cross section at N3LL.

QCD corrections to pair production of Type III Seesaw leptons at hadron colliders (2015)
Journal Article

If kinematically accessible, hadron collider experiments provide an ideal laboratory for the direct production of heavy lepton partners in Seesaw models. In the context of the Type III Seesaw Mechanism, the O(αs) rate and shape corrections are presen... Read More about QCD corrections to pair production of Type III Seesaw leptons at hadron colliders.

Comments on universal properties of entanglement entropy and bulk reconstruction (2015)
Journal Article

Entanglement entropy of holographic CFTs is expected to play a crucial role in the reconstruction of semiclassical bulk gravity. We consider the entanglement entropy of spherical regions of vacuum, which is known to contain universal contributions. A...

Topological aspects of generalized gravitational entropy (2015)
Journal Article

The holographic prescription for computing entanglement entropy requires that the bulk extremal surface, whose area encodes the amount of entanglement, satisfies a homology constraint. Usually this is stated as the requirement of a (spacelike) interp... Read More about Topological aspects of generalized gravitational entropy.

Two loop neutrino model and dark matter particles with global B−L symmetry (2014)
Journal Article

We study a two loop induced seesaw model with global U(1)B−L symmetry, in which we consider two component dark matter particles. The dark matter properties are investigated together with some phenomenological constraints such as electroweak precision...

Colonies of threaded rings in excitable media (2020)
Journal Article

A thring is a recent addition to the zoo of spiral wave phenomena found in excitable media and consists of a scroll ring that is threaded by a pair of counter-rotating scroll waves. This arrangement behaves as a particle that swims through the medium... Read More about Colonies of threaded rings in excitable media.

Updated constraints on velocity and momentum-dependent asymmetric dark matter (2016)
Journal Article

We present updated constraints on dark matter models with momentum-dependent or velocity-dependent interactions with nuclei, based on direct detection and solar physics. We improve our previous treatment of energy transport in the solar interior by d... Read More about Updated constraints on velocity and momentum-dependent asymmetric dark matter.

Matching next-to-leading order predictions to parton showers in supersymmetric QCD (2016)
Journal Article

We present a fully automated framework based on the FeynRules and MadGraph5_aMC@NLO programs that allows for accurate simulations of supersymmetric QCD processes at the LHC. Starting directly from a model Lagrangian that features squark and gluino in... Read More about Matching next-to-leading order predictions to parton showers in supersymmetric QCD.

Vector boson production in association with a jet at forward rapidities (2019)
Journal Article

Final states with a vector boson and a hadronic jet allow one to infer the Born-level kinematics of the underlying hard scattering process, thereby probing the partonic structure of the colliding protons. At forward rapidities, the parton collisions... Read More about Vector boson production in association with a jet at forward rapidities.

Multilepton signals of gauge mediated supersymmetry breaking at the LHC (2014)
Journal Article

We investigate multilepton LHC signals arising from electroweak processes involving sleptons. We consider the framework of general gauge mediated supersymmetry breaking, focusing on models where the low mass region of the superpartner spectrum consis...

Evolution in opening angle combining DGLAP and BFKL logarithms (2014)
Journal Article

We present an evolution equation which simultaneously sums the leading BFKL and DGLAP logarithms for the integrated gluon distribution in terms of a single variable, namely the emission angle of the gluon. This form of evolution is appropriate for Mo... Read More about Evolution in opening angle combining DGLAP and BFKL logarithms.

High-energy elastic and diffractive cross sections (2014)
Journal Article

We present a ‘global’ description of the wide variety of high-energy elastic and diffractive data that are presently available, particularly from the LHC experiments. The model is based on only one pomeron pole, but it includes multi-pomeron interact... Read More about High-energy elastic and diffractive cross sections.

Heavy neutrinos with dynamic jet vetoes: multilepton searches at √s = 14, 27, and 100 TeV (2019)
Journal Article

Heavy neutrinos (N) remain one of most promising explanations for the ori-gin of neutrinos’ tiny masses and large mixing angles. In light of broad advances in un-derstanding and modeling of hadron collisions at large momentum transfers, we revisit th...

Measurement of observables sensitive to coherence effects in hadronic Z decays with the OPAL detector at LEP (2015)
Journal Article

A study of QCD coherence is presented based on a sample of about 397,000 e+e− hadronic annihilation events collected at s√=91 GeV with the OPAL detector at LEP. The study is based on four recently proposed observables that are sensitive to coherence...

Dark neutrinos and a three-portal connection to the standard model (2020)
Journal Article

We introduce a dark neutrino sector which respects a hidden Uð1Þ0 gauge symmetry, subsequently broken by the vacuum expectation value of a dark scalar. The model is a self-consistent realization of an extended hidden sector that communicates with the... Read More about Dark neutrinos and a three-portal connection to the standard model.

Two scales in Bose–Einstein correlations (2016)
Journal Article

We argue that the secondaries produced in high-energy hadron collisions are emitted by small-size sources distributed over a much larger area in impact parameter space occupied by the interaction amplitude. That is, Bose–Einstein correlation of two e... Read More about Two scales in Bose–Einstein correlations.

Universality between vector-like and chiral quiver gauge theories: anomalies and domain walls (2020)
Journal Article

We study low-energy dynamics of [SU(N)]K chiral quiver gauge theories in connection with N = 1 super Yang-Mills (SYM) theory, and quantum chromodynamics with bi-fundamental fermions (QCD(BF)). These theories can be obtained by ZK orbifold projections... Read More about Universality between vector-like and chiral quiver gauge theories: anomalies and domain walls.

Constraining four-fermion operators using rare top decays (2019)
Journal Article

New physics can manifest itself by an appreciable increase of the decay rate of top quarks in rare flavour-changing final states. Exploiting the large top quark production rate at the LHC, we bound four-fermion operators contributing to non-resonant... Read More about Constraining four-fermion operators using rare top decays.

Recursion relations for anomalous dimensions in the 6d (2, 0) theory (2019)
Journal Article

We derive recursion relations for the anomalous dimensions of double-trace operators occurring in the conformal block expansion of four-point stress tensor correlators in the 6d (2, 0) theory, which encode higher-derivative corrections to supergravit...

Comments on Global Parton Analyses (2020)
Journal Article

We discuss the causes which can limit the accuracy of the predictions based on the conventional PDFs when including in global parton analyses the data at moderate scales μ. The first is the existence of power corrections O(Q20/μ2) due to the double c... Read More about Comments on Global Parton Analyses.
