Lepton number violation at colliders from kinematically inaccessible gauge bosons (2017)
Journal Article

We reevaluate the necessity of WRWR gauge bosons being kinematically accessible to test the left–right symmetric model (LRSM) at hadron colliders. In the limit that WRWR are too heavy, resonant production of sub-TeV Majorana neutrinos N can still pro...

Journal Article

This report was prepared in the context of the LPCC Electroweak Precision Measurements at the LHC WG (https://lpcc.web.cern.ch/lpcc/index.php?page=electroweak_wg) and summarizes the activity of a subgroup dedicated to the systematic comparison of pub...

Searching for Leptoquarks at IceCube and the LHC (2018)
Journal Article

In the light of recent experimental results from IceCube, LHC searches for scalar leptoquark, and the flavor anomalies RK and RK , we analyze two scalar leptoquark models with hypercharge Y ¼ 1=6 and Y ¼ 7=6. We consider the 53 high-energy starting e... Read More about Searching for Leptoquarks at IceCube and the LHC.

A generalised Davydov-Scott model for polarons in linear peptide chains (2017)
Journal Article

We present a one-parameter family of mathematical models describing the dynamics of polarons in periodic structures, such as linear polypeptides, which, by tuning the model parameter, can be reduced to the Davydov or the Scott model. We describe the... Read More about A generalised Davydov-Scott model for polarons in linear peptide chains.

Electroweak oblique parameters as a probe of the trilinear Higgs boson self-interaction (2017)
Journal Article

We calculate the two-loop contributions from a modified trilinear Higgs self-interaction, κλλSMvh3, to the electroweak oblique parameters S and T. Using the current bounds on S and T from electroweak measurements, we find the 95% C.L. constraint on t...

Precise predictions for dijet production at the LHC (2017)
Journal Article

We present the calculation of dijet production, doubly differential in dijet mass m j j and rapidity difference | y ∗ | , at leading color in all partonic channels at next-to-next-to-leading order (NNLO) in perturbative QCD. We consider the long-stan... Read More about Precise predictions for dijet production at the LHC.

Wilson Loop Form Factors: A New Duality (2018)
Journal Article

We find a new duality for form factors of lightlike Wilson loops in planar N = 4 super-Yang-Mills theory. The duality maps a form factor involving an n-sided lightlike polygonal super-Wilson loop together with m external on-shell states, to the same...

The NNLO QCD corrections to Z boson production at large transverse momentum (2016)
Journal Article

The transverse momentum distribution of massive neutral vector bosons can be measured to high accuracy at hadron colliders. The transverse momentum is caused by a partonic recoil, and is determined by QCD dynamics. We compute the single and double-di...

Entanglement of self-interacting scalar fields in an expanding spacetime (2016)
Journal Article

We evaluate self-interaction effects on the quantum correlations of field modes of opposite momenta for scalar $\lambda \phi^4$ theory in a two-dimensional asymptotically flat Robertson-Walker spacetime. Such correlations are encoded both in the von... Read More about Entanglement of self-interacting scalar fields in an expanding spacetime.

Black hole thermodynamics with conical defects (2017)
Journal Article

Recently we have shown [1] how to formulate a thermodynamic first law for a single (charged) accelerated black hole in AdS space by fixing the conical deficit angles present in the spacetime. Here we show how to generalise this result, formulating th... Read More about Black hole thermodynamics with conical defects.

What is the scale of new physics behind the B-flavour anomalies? (2017)
Journal Article

Motivated by the recent hints of lepton flavour non-universality in B-meson semi-leptonic decays, we study the constraints of perturbative unitarity on the new physics interpretation of the anomalies in b→cℓν¯b→cℓν¯ and b→sℓℓ¯b→sℓℓ¯ transitions. With... Read More about What is the scale of new physics behind the B-flavour anomalies?.

Higgs-boson masses and mixing matrices in the NMSSM: analysis of on-shell calculations (2017)
Journal Article

We analyze the Higgs-boson masses and mixing matrices in the NMSSM based on an on-shell (OS) renormalization of the gauge-boson and Higgs-boson masses and the parameters of the top/scalar top sector. We compare the implementation of the OS calculatio... Read More about Higgs-boson masses and mixing matrices in the NMSSM: analysis of on-shell calculations.

Enhancement of the lepton flavor violating Higgs boson decay rates from SUSY loops in the inverse seesaw model (2016)

Elastic scattering and diffractive dissociation in the light of LHC data (2015)
Journal Article

We study the behavior of elastic and diffractive proton dissociation cross sections at high energy. First, we describe what would be expected to be observed at the Large Hadron Collider (LHC) based on conventional Regge theory. We emphasize the tensi...

Charm and beauty quark masses in the MMHT2014 global PDF analysis (2016)
Journal Article

We investigate the variation in the MMHT2014 PDFs when we allow the heavy-quark masses mcmc and mbmb to vary away from their default values. We make PDF sets available in steps of Δmc=0.05 GeVΔmc=0.05 GeV and Δmb=0.25 GeVΔmb=0.25 GeV , and present th... Read More about Charm and beauty quark masses in the MMHT2014 global PDF analysis.

The exclusive J/ψ process at the LHC tamed to probe the low x gluon (2016)
Journal Article

The perturbative QCD expansion for J/ψ photoproduction appears to be unstable: the NLO correction is large (and of opposite sign) to the LO contribution. Moreover, the predictions are very sensitive to the choice of factorisation and renormalisation... Read More about The exclusive J/ψ process at the LHC tamed to probe the low x gluon.

Optimal choice of factorization scales for the description of jet production at the LHC (2017)
Journal Article

To obtain more precise parton distribution functions (PDFs) it is important to include data on inclusive high transverse energy jet production in the global parton analyses. These data have high statistics and the NNLO terms in the perturbative QCD (... Read More about Optimal choice of factorization scales for the description of jet production at the LHC.

The role of flavon cross couplings in leptonic flavour mixing (2016)
Journal Article

In models with discrete flavour symmetries, flavons are critical to realise specific flavour structures. Leptonic flavour mixing originates from the misalignment of flavon vacuum expectation values which respect different residual symmetries in the c...
