Bootstrapping line defects with O(2) global symmetry

Journal of High Energy Physics, 2022
We use the numerical bootstrap to study conformal line defects with O(2) global symmetry. Our results are very general and capture in particular conformal line defects originating from bulk CFTs with a continuous global symmetry, which can either be ...

Group theory analysis of phonons in two-dimensional transition metal dichalcogenides [PDF]

, 2014
Transition metal dichalcogenides (TMDCs) have emerged as a new two-dimensional material’s field since the monolayer and few-layer limits show different properties when compared to each other and to their respective bulk materials.

The strangest proton?

European Physical Journal C: Particles and Fields, 2020
We present an improved determination of the strange quark and antiquark parton distribution functions of the proton by means of a global QCD analysis that takes into account a comprehensive set of strangeness-sensitive measurements: charm-tagged cross ...

Group theory for structural analysis and lattice vibrations in phosphorene systems [PDF]

, 2014
Group theory analysis for two-dimensional elemental systems related to phosphorene is presented, including (i) graphene, silicene, germanene, and stanene; (ii) their dependence on the number of layers; and (iii) their two possible stacking arrangements ...

Bootstrapping Coulomb and Higgs branch operators

Journal of High Energy Physics, 2021
We apply the numerical conformal bootstrap to correlators of Coulomb and Higgs branch operators in 4d N $$ \mathcal{N} $$ = 2 superconformal theories. We start by revisiting previous results on single correlators of Coulomb branch operators.

Seeking SUSY fixed points in the 4 − ϵ expansion

Journal of High Energy Physics, 2021
We use the 4 − ϵ expansion to search for fixed points corresponding to 2 + 1 dimensional N $$ \mathcal{N} $$ =1 Wess-Zumino models of N Φ scalar superfields interacting through a cubic superpotential. In the N Φ = 3 case we classify all SUSY fixed points

Five-loop renormalisation of QCD in covariant gauges

Journal of High Energy Physics, 2017
We present the complete set of vertex, wave function and charge renormalisation constants in QCD in a general simple gauge group and with the complete dependence on the covariant gauge parameter ξ in the minimal subtraction scheme of conventional ...

Group testing: an information theory perspective [PDF]

Foundations and Trends in Communications and Information Theory, 2019
The group testing problem concerns discovering a small number of defective items within a large population by performing tests on pools of items. A test is positive if the pool contains at least one defective, and negative if it contains no defectives ...

Sickle Cell Disease Is an Inherent Risk for Asthma in a Sibling Comparison Study

Pediatric Blood &Cancer, EarlyView.
ABSTRACT Introduction Sickle cell disease (SCD) and asthma share a complex relationship. Although estimates vary, asthma prevalence in children with SCD is believed to be comparable to or higher than the general population. Determining whether SCD confers an increased risk for asthma remains challenging due to overlapping symptoms and the ...

A phenomenological analysis of LHC neutrino scattering at NLO accuracy matched to parton showers

European Physical Journal C: Particles and Fields
We perform a detailed phenomenological study of high-energy neutrino deep inelastic scattering (DIS) focused on LHC far-forward experiments such as FASER $$\nu $$ ν and SND@LHC.
