Core formation from self-heating dark matter [DESY-18-040; arXiv:1803.09762] Journal of cosmology and astroparticle physics 2018(07), 013 - 013 (2018) [10.1088/1475-7516/2018/07/013]   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.

The fate of Little Higgs Models with LHC Run 2 Data International Conference on High Energy Physics 2018, ICHEP 2018, SeoulSeoul, South Korea, 4 Jul 2018 - 11 Jul 2018   Little Higgs models - which can most easily be thought of as a variant ofcomposite Higgs models - explain a light Higgs boson at 125 GeV as anpseudo-Nambu-Goldstone boson of a spontaneously broken global symmetry.The mechanism of collective symmetry breaking shifts the UV scale ofthese models to the 10 TeV scale and higher. T-parity is introduced asa discrete symmetry to remove tree-level constraints on the electroweakprecision data.

Matching Threshold and Continuum for Exclusive Top Pairs International Conference on High Energy Physics 2018, ICHEP 2018, SeoulSeoul, South Korea, 4 Jul 2018 - 11 Jul 2018   The threshold scan at future lepton colliders is the most preciseknown method to determine the top quark mass (well below 100 MeV), afundamental parameter of the Standard Model that co-determines thestability properties of the electroweak vacuum. We present a new method tomatch the continuum next-to-leading order QCD corrections with thenext-to-leading logarithmic resummation of the Coulomb singularities of thequasi-toponium bound state at threshold where fixed-order perturbationtheory is invalid.

The role of positron polarization for the initial 250 GeV stage of the ILC International Conference on High Energy Physics 2018, ICHEP 2018, SeoulSeoul, South Korea, 4 Jul 2018 - 11 Jul 2018   The International Linear Collider is now proposed with a staged machine design, with the first stage at $\sqrt{s}$ = 250 GeV and an integrated luminosity goal of 2 ab$^{-1}$. One of the questions for the machine design is the importance of positron polarization. [...] OpenAccess: PDF PDF (PDFA); 2018-07-0310:16 [PUBDB-2018-02509] Poster Westphal, A.

Exploration of the Higgs sector after its discovery 197 pp. (2018) [10.3204/PUBDB-2018-02379] = Dissertation, Universitat Autonoma de Barcelona, 2018   The discovery of the Higgs boson culminates a 40-year long hunt and completes a theoretical framework under which almost all collider data can be consistently explained. At the same time, paradoxically, the confirmation of an apparent mass gap above the electroweak scale exacerbates the problem of the electroweak hierarchy [...] OpenAccess: PDF; 2018-06-2123:17 [PUBDB-2018-02347] Conference Presentation Sala, F.

Proposal of new ALP searches at the LHC 14TH PATRAS WORKSHOP ON AXIONS, WIMPS AND WISPS, Patras 2018, HamburgHamburg, DESY, 18 Jun 2018 - 22 Jun 2018   ALPs that couple to gluons are predicted both to solve the strong CP problem as well as in composite Higgs models (Higgs pseudo-Goldstone partners) and in Supersymmetry (R-axion).I will discuss unexplored avenues in the LHC phenomenology resulting from such gluon-ALP couplings. I will derive a new LHC bound on ALPs from diphoton cross-section measurements, and show it is the strongest existing limit in the mass window 10-65 GeV.
