First order Galilean superfluid dynamics (2017)
Journal Article

We study dynamics of an (anomalous) Galilean superfluid up to first order in derivative expansion, both in parity-even and parity-odd sectors. We construct a relativistic system—null superfluid, which is a null fluid (introduced in N. Banerjee, S. Du... Read More about First order Galilean superfluid dynamics.

Single Jet Inclusive Production for the Individual Jet pT Scale Choice at the LHC (2017)
Journal Article

We study the single jet inclusive cross section up to next-to-next-to leading order in perturbative QCD, implemented in the parton-level event generator NNLOJET. Our results are fully differential in the jet transverse momentum and rapidity, and we a... Read More about Single Jet Inclusive Production for the Individual Jet pT Scale Choice at the LHC.

NLO QCD+EW predictions for 2ℓ2ν diboson signatures at the LHC (2017)
Journal Article

We present next-to-leading order (NLO) calculations including QCD and electroweak (EW) corrections for 2ℓ2ν diboson signatures with two opposite-charge leptons and two neutrinos. Specifically, we study the processes pp→e+μ−νeν¯¯¯μpp→e+μ−νeν¯μ and pp→... Read More about NLO QCD+EW predictions for 2ℓ2ν diboson signatures at the LHC.

The five-loop Beta function for a general gauge group and anomalous dimensions beyond Feynman gauge (2017)
Journal Article

We focus on a non-abelian gauge field coupled to a single (but general) representation of a family of Nf fermions. By using the same machinery that had allowed us to evaluate the sub-leading large-Nf term of the five-loop Beta function earlier, we he...

Two-loop helicity amplitudes for the production of two off-shell electroweak bosons in quark-antiquark collisions (2014)
Journal Article

Knowledge of two-loop QCD amplitudes for processes qq′→V1V2→(l1l¯′1)(l2l¯′2)qq′→V1V2→(l1l¯1′)(l2l¯2′) is important for improving the theoretical description of four-lepton production in hadron collisions. In this paper we compute these helicity ampli... Read More about Two-loop helicity amplitudes for the production of two off-shell electroweak bosons in quark-antiquark collisions.

QCD corrections to ZZ production in gluon fusion at the LHC (2015)
Journal Article

We compute the next-to-leading-order QCD corrections to the production of two Z -bosons in the annihilation of two gluons at the LHC. Being enhanced by a large gluon flux, these corrections provide a distinct and, potentially, the dominant part of th... Read More about QCD corrections to ZZ production in gluon fusion at the LHC.

ZZ production in gluon fusion at NLO matched to parton shower (2017)
Journal Article

We present a calculation of the next-to-leading order QCD corrections to the hadroproduction process gg→ZZ→e+e−μ+μ−, matched to the parton shower in the POWHEG framework. We take advantage of the POWHEG BOX tool for the implementation and rely on PYT... Read More about ZZ production in gluon fusion at NLO matched to parton shower.

Review of Particle Physics (2016)
Journal Article

The Review summarizes much of particle physics and cosmology. Using data from previous editions, plus 3,062 new measurements from 721 papers, we list, evaluate, and average measured properties of gauge bosons and the recently discovered Higgs boson,... Read More about Review of Particle Physics.

Integrability of generalised type II defects in affine Toda field theory (2017)
Journal Article

The Liouville integrability of the generalised type II defects is investigated. Full integrability is not considered, only the existence of an infinite number of conserved quantities associated with a system containing a defect. For defects in affine...

Searching for processes with invisible particles using a matrix element-based method (2018)
Journal Article

We propose a fully flexible method to discriminate between signal and background using a matrix element-based method in the presence of multiple invisible particles. The proposed method performs a mapping of the measured final state onto an observabl... Read More about Searching for processes with invisible particles using a matrix element-based method.

Exponential suppression of the cosmological constant in nonsupersymmetric string vacua at two loops and beyond (2017)
Journal Article

Two independent criteria are presented that together guarantee exponential suppression of the two-loop cosmological constant in nonsupersymmetric heterotic strings. They are derived by performing calculations in both the full string theory and in its...

Two-loop helicity amplitudes for the production of two off-shell electroweak bosons in gluon fusion (2015)
Journal Article

We compute the part of the two-loop virtual amplitude for the process gg→V1V2→(l1l¯′2)(l2l¯′2)gg→V1V2→(l1l¯2′)(l2l¯2′) , where V 1,2 are arbitrary electroweak gauge bosons, that receives contributions from loops of massless quarks. Invariant masses o... Read More about Two-loop helicity amplitudes for the production of two off-shell electroweak bosons in gluon fusion.

Towards a fully massive five-flavor scheme (2018)
Journal Article

In this paper, we explore first necessary steps to construct a fully massive version of a variable-flavor number scheme. In particular we focus, as an example, on an extension of the five-flavor scheme, where instead of neglecting explicit initial st... Read More about Towards a fully massive five-flavor scheme.

Jet-vetoed Higgs cross section in gluon fusion at N3LO+NNLL with small-R resummation (2016)
Journal Article

We present new results for the jet-veto efficiency and zero-jet cross section in Higgs production through gluon fusion. We incorporate the N3LO corrections to the total cross section, the NNLO corrections to the 1-jet rate, NNLL resummation for the j...

The Higgs transverse momentum spectrum with finite quark masses beyond leading order (2016)
Journal Article

We apply the leading-log high-energy resummation technique recently derived by some of us to the transverse momentum distribution for production of a Higgs boson in gluon fusion. We use our results to obtain information on mass-dependent corrections... Read More about The Higgs transverse momentum spectrum with finite quark masses beyond leading order.

Reweighting parton showers (2016)
Journal Article

We report on the possibility of reweighting parton-shower Monte Carlo predictions for scale variations in the parton-shower algorithm. The method is based on a generalization of the Sudakov veto algorithm. We demonstrate the feasibility of this appro... Read More about Reweighting parton showers.

Universal features of BPS strings in six-dimensional SCFTs (2018)
Journal Article

In theories with extended supersymmetry the protected observables of UV superconformal fixed points are found in a number of contexts to be encoded in the BPS solitons along an IR Coulomb-like phase. For six-dimensional SCFTs such a role is played by... Read More about Universal features of BPS strings in six-dimensional SCFTs.

Higgs boson plus dijets: higher order corrections (2017)
Journal Article

The gluon fusion component of Higgs-boson production in association with dijets is of particular interest because it both (a) allows for a study of the CP-structure of the Higgs-boson couplings to gluons, and (b) provides a background to the otherwis...

Phase transitions and baryogenesis from decays (2017)
Journal Article

We study scenarios in which the baryon asymmetry is generated from the decay of a particle whose mass originates from the spontaneous breakdown of a symmetry. This is realized in many models, including low-scale leptogenesis and theories with classic... Read More about Phase transitions and baryogenesis from decays.

Precise predictions for the angular coefficients in Z-boson production at the LHC (2017)
Journal Article

The angular distributions of lepton pairs in the Drell-Yan process can provide rich information on the underlying QCD production mechanisms. These dynamics can be parameterised in terms of a set of frame dependent angular coefficients, Ai=0,…,7, whic...
