Volume Dependence of NBody Bound States
[arXiv:1701.00279]
We derive the finitevolume correction to the binding energy of an N particle quantum bound state in a cubic periodic volume. Our results are applicable to bound states with arbitrary composition and total angular momentum, and in any number of spatial dimensions. [...]

Prompt photon production and photonjet correlations at the LHCi
[MSTP1709; arXiv:1709.04154]
Nexttoleading order predictions matched to parton showers are compared with recent ATLAS data on isolated photon production and CMS data on associated photon and jet production in pp and pPb collisions at different centreofmass energies of the LHC. We find good agreement and, as expected, considerably reduced scale uncertainties compared to previous theoretical calculations. [...]

Fierzcomplete NJL model study. II. Toward the fixedpoint and phase structure of hot and dense twoflavor QCD
[arXiv:1801.08338]
NambuJonaLasiniotype models are often employed as lowenergy models for the theory of the strong interaction to analyze its phase structure at finite temperature and quark chemical potential. In particular, at low temperature and large chemical potential, where the application of fully firstprinciples approaches is currently difficult at best, this class of models still plays a prominent role in guiding our understanding of the dynamics of dense stronginteraction matter.

Elliptic flow of electrons from beautyhadron decays extracted from PbPb collision data at $\sqrt{s_{\rm NN}}$ = 2.76 TeV
[arXiv:1705.00161]
We present a calculation of the elliptic flow of electrons from beautyhadron decays in semicentral Pb–Pb collisions at centreofmass energy per colliding nucleon pair, represented as $\sqrt{s_\mathrm{NN}}$ , of 2.76 TeV. The result is obtained by the subtraction of the charmquark contribution in the elliptic flow of electrons from heavyflavour hadron decays in semicentral Pb–Pb collisions at $\sqrt{s_\mathrm{NN}} = 2.76\ \hbox {TeV}$ recently made publicly available by the ALICE collaboration..

Discriminating WIMPnucleus response functions in present and future XENONlike direct detection experiments
[INTPUB18006; arXiv:1802.04294]
The standard interpretation of directdetection limits on dark matter involves particular assumptions of the underlying WIMPnucleus interaction, such as, in the simplest case, the choice of a Helm form factor that phenomenologically describes an isoscalar spinindependent interaction. In general, the interaction of dark matter with the target nuclei may well proceed via different mechanisms, which would lead to a different shape of the corresponding nuclear structure factors as a function of the momentum transfer q.

Polyakov loop fluctuations in the presence of external fields
[arXiv:1801.08040]
We study the implications of the spontaneous and explicit Z(3) center symmetry breaking for the Polyakov loop susceptibilities. To this end, ratios of the susceptibilities of the real and imaginary parts, as well as of the modulus of the Polyakov loop are computed within an effective model using a color group integration scheme.

Doublefolding potentials from chiral effective field theory
[arXiv:1708.02527]
The determination of nucleus–nucleus potentials is important not only to describe the properties of the colliding system, but also to extract nuclearstructure information and for modelling nuclear reactions for astrophysics. We present the first determination of doublefolding potentials based on chiral effective field theory at leading, nexttoleading, and nexttonexttoleading order. [...]

Threebody spectrum in a finite volume: the role of cubic symmetry
[arXiv:1802.03362; JLABTHY182646]
The threeparticle quantization condition is partially diagonalized in the centerofmass frame by using cubic symmetry on the lattice. To this end, instead of spherical harmonics, the kernel of the BetheSalpeter equation for particledimer scattering is expanded in the basis functions of different irreducible representations of the octahedral group.

Threshold Effects and the Line Shape of the X(3872) in Effective Field Theory
[arXiv:1804.00375]
Latest measurements suggest that the X(3872) mass lies less than 200 keV away from the D0D¯0* threshold, reenforcing its interpretation as a loosely bound mesonic molecule. This observation implies that in processes like D0D¯0π0 production, threshold effects could disguise the actual pole position of the X(3872). [...]
