 2019-07-1211:17 [GSI-2019-00793] Journal Article et al Low-lying dipole strength in the well-deformed nucleus $^{156}$Gd Nuclear physics / A 987, 79 - 89 (2019) [10.1016/j.nuclphysa.2019.03.014] 2019-05-3113:40 [GSI-2019-00697] Report/Journal Article Lee, D. Volume Dependence of N-Body Bound States [arXiv:1701.00279] Physics letters / B B B779, 9 - 15 (2018) [10.1016/j.physletb.2018.01.060] We derive the finite-volume 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 photon-jet correlations at the LHCi [MS-TP-17-09; arXiv:1709.04154] Journal of high energy physics 1803(3), 81 (2018) [10.1007/JHEP03(2018)081] Next-to-leading 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 centre-of-mass energies of the LHC. We find good agreement and, as expected, considerably reduced scale uncertainties compared to previous theoretical calculations.

Toward the fixed-point and phase structure of hot and dense two-flavor QCD [arXiv:1801.08338] Physical review / D D D97(7), 076010 (2018) [10.1103/PhysRevD.97.076010] Nambu-Jona-Lasinio-type models are often employed as low-energy 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 first-principles approaches is currently difficult at best, this class of models still plays a prominent role in guiding our understanding of the dynamics of dense strong-interaction matter.

The result is obtained by the subtraction of the charm-quark contribution in the elliptic flow of electrons from heavy-flavour hadron decays in semi-central Pb–Pb collisions at $\sqrt{s_\mathrm{NN}} = 2.76\ \hbox {TeV}$ recently made publicly available by the ALICE collaboration.. OpenAccess: PDF; 2019-05-2812:47 [GSI-2019-00690] Report/Journal Article et al Discriminating WIMP-nucleus response functions in present and future XENON-like direct detection experiments [INT-PUB-18-006; arXiv:1802.04294] Physical review / D D D97(10), 103532 (2018) [10.1103/PhysRevD.97.103532] The standard interpretation of direct-detection limits on dark matter involves particular assumptions of the underlying WIMP-nucleus interaction, such as, in the simplest case, the choice of a Helm form factor that phenomenologically describes an isoscalar spin-independent 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. [...] OpenAccess: PDF; 2019-05-2810:20 [GSI-2019-00689] Report/Journal Article et al Polyakov loop fluctuations in the presence of external fields [arXiv:1801.08040] Physical review / D D D97(11), 114006 (2018) [10.1103/PhysRevD.97.114006] 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. [...] OpenAccess: PDF; 2019-05-2810:03 [GSI-2019-00688] Report/Journal Article et al Double-folding potentials from chiral effective field theory [arXiv:1708.02527] Physics letters / B B B782, 668 - 674 (2018) [10.1016/j.physletb.2018.05.084] The determination of nucleus–nucleus potentials is important not only to describe the properties of the colliding system, but also to extract nuclear-structure information and for modelling nuclear reactions for astrophysics. We present the first determination of double-folding potentials based on chiral effective field theory at leading, next-to-leading, and next-to-next-to-leading order. [...] OpenAccess: PDF; 2019-05-2809:53 [GSI-2019-00687] Report/Journal Article et al Three-body spectrum in a finite volume: the role of cubic symmetry [arXiv:1802.03362; JLAB-THY-18-2646] Physical review / D D 97(11), 114508 (2018) [10.1103/PhysRevD.97.114508] The three-particle quantization condition is partially diagonalized in the center-of-mass frame by using cubic symmetry on the lattice. To this end, instead of spherical harmonics, the kernel of the Bethe-Salpeter equation for particle-dimer scattering is expanded in the basis functions of different irreducible representations of the octahedral group. [...] OpenAccess: PDF; 2019-05-2809:47 [GSI-2019-00686] Report/Journal Article Hammer, H.-W. Threshold Effects and the Line Shape of the X(3872) in Effective Field Theory [arXiv:1804.00375] Physical review / D D D98(1), 014032 (2018) [10.1103/PhysRevD.98.014032] 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). [...] OpenAccess: PDF;
