Probing photodissociation dynamics using ring polymer molecular dynamics The journal of chemical physics 150(11), 114105 (2019) [10.1063/1.5086218]   The performance of the ring polymer molecular dynamics (RPMD) approach to simulate typical photodissociation processes is assessed. The correct description of photodissociation requires the calculation of correlation functions or expectation values associated with non-equilibrium initial conditions, which was shown to be possible with RPMD very recently [J.

A. Improved constraints on the mixing and mass of $Z'$ bosons from resonant diboson searches at the LHC at $\sqrt{s}=13$ TeV and predictions for Run II [DESY-18-170; arXiv:1809.08933] Physical review / D 98(9), 095029 (2018) [10.1103/PhysRevD.98.095029]   New neutral vector bosons Z′ decaying to charged gauge boson pairs W$^+$W$^-$ are predicted in many scenarios of new physics, including models with an extended gauge sector such as E6, left-right symmetric ZLRS′ and the sequential standard model ZSSM′. For these benchmark models we calculate and present theoretical expectations for different values of the Z′ mass M2 and mixing parameter ξ.

Time-resolved x-ray/optical pump-probe simulations on $\mathrm{N_2}$ molecules Structural dynamics 6(2), 024101 (2019) [10.1063/1.5053995]   The dynamics of $N_2^{2+}$ dications after x-ray-induced Auger decay and their probing with a delayed infrared probe pulse are theoretically investigated based on a quantum-mechanical model including all relevant electronic states for which wave-packet calculations on ab-initio potential energy curves are performed. Our results demonstrate that the $N_2^{2+}$ yield modulated by the delay of the probe pulse contains dynamical information on the wave-packet evolution in the quasi-bound final electronic states [...] OpenAccess: PDF PDF (PDFA); 2019-03-1811:32 [PUBDB-2019-01570] Report/Journal Article Riemann, T. Scalar 1-loop Feynman integrals as meromorphic functions in space-time dimension d [DESY 17-079, HCMUS-19-01, KW 18-004, arXiv:1812.10975] Physics letters / B 791, 257 - 264 (2019) [10.1016/j.physletb.2019.02.044]   The long-standing problem of representing the general massive one-loop Feynman integral as a meromorphic function of the space-time dimension d has been solved for the basis of scalar one- to four-point functions with indices one. In 2003 the solution of difference equations in the space-time dimension allowed to determine the necessary classes of special functions: self-energies need ordinary logarithms and Gauss hypergeometric functions $_{2}F_1$, vertices need additionally Kampé de Fériet-Appell functions $F_1$, and box integrals also Lauricella-Saran functions $F_S$ [...] OpenAccess: PDF PDF (PDFA); 2019-03-1511:37 [PUBDB-2019-01557] Journal Article et al Virtual Archaeology of Altered Paintings: Multiscale Chemical Imaging Tools Elements 12(1), 39 - 44 (2016) [10.2113/gselements.12.1.39]   Understanding how painted works of art were constructed, layer-by-layer, requires a range of macroscopic and microscopic X-ray and infrared-based analytical methods. Deconstructing complex assem-blies of paints horizontally across a picture and vertically through it provides insight into the detailed production process of the art work and on the painting techniques and styles of its maker.

We use realistic evolved non-perturbative fragmentation functions obtained from fits to B-meson production in $e^+ e^-$ annihilation and compare our results for transverse-momentum and rapidity distributions with recent experimental data from the CMS and the LHCb collaborations at the CERN LHC.

The correction is represented in terms of iterated incomplete elliptic integrals.

This analysis uses atmospheric neutrinos from the full sky with reconstructed energies between 5.6 and 56 GeV to search for a statistical excess of cascadelike neutrino events which are the signature of $ν_τ$ interactions [...] OpenAccess: PDF PDF (PDFA); 2019-03-1411:06 [PUBDB-2019-01535] Journal Article et al Relativistic Jet Simulations of the Weibel Instability in the Slab Model to Cylindrical Jets with Helical Magnetic Fields Galaxies 7(1), 29 (2019) [10.3390/galaxies7010029]   The particle-in-cell (PIC) method was developed to investigate microscopic phenomena, and with the advances in computing power, newly developed codes have been used for several fields, such as astrophysical, magnetospheric, and solar plasmas. PIC applications have grown extensively, with large computing powers available on supercomputers such as Pleiades and Blue Waters in the US. [...] OpenAccess: PDF PDF (PDFA);
