 2018-06-2210:38 [PUBDB-2018-02351] Report/Journal Article et al Combination and QCD analysis of charm and beauty production cross-section measurements in deep inelastic $ep$ scattering at HERA [DESY-18-037; arXiv:1804.01019]   Measurements of open charm and beauty production cross sections in deep inelastic $ep$ scattering at HERA from the H1 and ZEUS Collaborations are combined. Reduced cross sections are obtained in the kinematic range of negative four-momentum transfer squared of the photon $2.5$ GeV$^2\leq Q^2 \leq 2000$ GeV$^2$ and Bjorken scaling variable $3\cdot 10^{-5}\leq x_{\text{Bj}} \leq 5 \cdot 10^{-2}$.

We use the formulation of Curci and Veneziano with clover-improved Wilson fermions. [...] OpenAccess: PDF PDF (PDFA); 2018-06-1312:34 [PUBDB-2018-02264] Report/Journal Article et al Model-independent comparison of annual modulation and total rate with direct detection experiments [DESY-18-028; TTK-18-08; arXiv:1802.10175; DESY-18-028; TTK-18-08] The relative sensitivity of different direct detection experiments depends sensitively on the astrophysical distribution and particle physics nature of dark matter, prohibiting a model-independent comparison. The situation changes fundamentally if two experiments employ the same target material. [...] Restricted: PDF PDF (PDFA); 2018-06-1311:09 [PUBDB-2018-02263] Preprint/Report Garcia-Cely, C. Core formation from self-heating dark matter [DESY-18-040; arXiv:1803.09762]   Cosmological simulations of the $\Lambda$CDM model suggest that the dark matter halos of dwarf galaxies are denser in their center than what observational data of such galaxies imply. In this letter, we propose a novel solution to this problem by invoking a certain class of dark matter self-heating processes. [...] OpenAccess: PDF PDF (PDFA); 2018-06-1310:52 [PUBDB-2018-02262] Report/Journal Article Stefaniak, T. Constraining extended scalar sectors at the LHC and beyond [DESY-18-031; arXiv:1803.03594] Modern physics letters / A 33(10n11), 1830007 - (2018) [10.1142/S0217732318300070]   We give a brief overview of beyond the Standard Model (BSM) theories with an extended scalar sector and their phenomenological status in the light of recent experimental results. We discuss the relevant theoretical and experimental constraints, and show their impact on the allowed parameter space of two specific models: the real scalar singlet extension of the Standard Model (SM) and the Inert Doublet Model. [...] Restricted: PDF PDF (PDFA); 2018-06-1310:38 [PUBDB-2018-02260] Report/Journal Article et al Top-philic dark matter within and beyond the WIMP paradigm [DESY-18-018; TUM-HEP 1131-18; TTK-18-05; arXiv:1802.00814] Physical review / D 97(7), 075002 (2018) [10.1103/PhysRevD.97.075002]   We present a comprehensive analysis of top-philic Majorana dark matter that interacts via a colored t-channel mediator. Despite the simplicity of the model -- introducing three parameters only -- it provides an extremely rich phenomenology allowing to accommodate the relic density for a large range of coupling strengths spanning over six orders of magnitude. [...] OpenAccess: PDF PDF (PDFA); 2018-06-1310:34 [PUBDB-2018-02259] Preprint/Report et al The seven-gluon amplitude in multi-Regge kinematics beyond leading logarithmic accuracy [DESY-18-009; CERN-TH-2018-016, CP3-18-06; SLAC-PUB-17220; arXiv:1801.10605 ]   We present an all-loop dispersion integral, well-defined to arbitrary logarithmic accuracy, describing the multi-Regge limit of the 2->5 amplitude in planar N=4 super Yang-Mills theory. It follows from factorization, dual conformal symmetry and consistency with soft limits, and specifically holds in the region where the energies of all produced particles have been analytically continued. [...] OpenAccess: PDF PDF (PDFA); 2018-06-1310:21 [PUBDB-2018-02257] Report/Journal Article Patel, K. M. Flavor physics without flavor symmetries [DESY-17-220; arXiv:1712.06862] Physical review / D 97(7), 075019 (2018) [10.1103/PhysRevD.97.075019]   We quantitatively analyze a quark-lepton flavour model derived from a six-dimensional supersymmetric theory with $SO(10)\times U(1)$ gauge symmetry, compactified on an orbifold with magnetic flux. Two bulk $\mathbf{16}$-plets charged under the $U(1)$ provide the three quark-lepton generations whereas two uncharged $\mathbf{10}$-plets yield two Higgs doublets. [...] OpenAccess: PDF PDF (PDFA); 2018-06-1310:18 [PUBDB-2018-02256] Report/Journal Article et al The fate of the littlest Higgs model with $T$-parity under 13 TeV LHC data [DESY-17-192; arXiv:1801.06499] Journal of high energy physics 1805(05), 049 (2018) [10.1007/JHEP05(2018)049]   We exploit all LHC available Run 2 data at center-of-mass energies of 8 and 13 TeV for searches for physics beyond the Standard Model. We scrutinize the allowed parameter space of Little Higgs models with the concrete symmetry of T-parity by providing comprehensive analyses of all relevant production channels of heavy vectors, top partners, heavy quarks and heavy leptons and all phenomenologically relevant decay channels.

From spinning conformal blocks to matrix Calogero-Sutherland models [DESY-17-177; NORDITA-2017-105; arXiv:1711.02022] Journal of high energy physics 1804(04), 052 (2018) [10.1007/JHEP04(2018)052]   In this paper we develop further the relation between conformal four-point blocks involving external spinning fields and Calogero-Sutherland quantum mechanics with matrix-valued potentials. To this end, the analysis of [1] is extended to arbitrary dimensions and to the case of boundary two-point functions. [...] OpenAccess: PDF PDF (PDFA);
