One jet to rule them all: monojet constraints and invisible decays of a 750 GeV diphoton resonance
Daniele Barducci, Andreas Goudelis, Suchita Kulkarni +1
The ATLAS and CMS collaborations recently reported a mild excess in the diphoton final state pointing to a resonance with a mass of around 750 GeV and a potentially large width. We…
Direct detection prospects of dark vectors with xenon-based dark matter experiments
Haipeng An, Kaixuan Ni, Maxim Pospelov +2
Dark matter experiments primarily search for the scattering of WIMPs on target nuclei of well shielded underground detectors. The results from liquid scintillator experiments furth…
GravitinoPack and late decays involving gravitinos
Helmut Eberl, Vassilis C. Spanos
In this talk, we present the package GravitinoPack that calculates decays of unstable supersymmetric particles, involving gravitinos in the final or initial state. If the gravitino…
Neutralino dark matter and naturalness of the electroweak scale
Geneviève Bélanger, Cédric Delaunay, Andreas Goudelis
If weak scale supersymmetry (SUSY) is to somehow explain the radiative stability of the Higgs boson mass, it is likely that non-minimal variants of SUSY models should be considered…
A light particle solution to the cosmic lithium problem
Andreas Goudelis, Maxim Pospelov, Josef Pradler
We point out that the cosmological abundance of Li can be reduced down to observed values if during its formation Big Bang Nucleosynthesis is modified by the presence of ligh…
Etaprime interactions with nucleons and nuclei
Steven D. Bass, Pawel Moskal
We summarise recent progress in theory and experiment towards understanding etaprime meson interactions with nucleons and nuclei. Highlights include the production mechanism of eta…
GravitinoPack and decays of supersymmetric metastable particles
Helmut Eberl, Vassilis C. Spanos
We present the package GravitinoPack that calculates the two- and three-body decays of unstable supersymmetric particles involving the gravitino in the final or initial state. In a…
Strong Couplings of Charmed Mesons and Quarkonia
Wolfgang Lucha, Dmitri Melikhov, Hagop Sazdjian +1
We extract the strong coupling constants of three mesons, each of which is composed of either two charm quarks or one charm quark and one light (i.e., , , or ) quark, from…
Reconciling the 2 TeV Excesses at the LHC in a Linear Seesaw Left-Right Model
Frank F. Deppisch, Lukas Graf, Suchita Kulkarni +4
We interpret the 2 TeV excesses at the LHC in a left-right symmetric model with Higgs doublets and spontaneous -parity violation. The light neutrino masses are understood via a…
Light Pseudoscalar Mesons in Bethe-Salpeter Equation with Instantaneous Interaction
Wolfgang Lucha, Franz F. Schöberl
The light pseudoscalar mesons play a twofold role: they may or have to be regarded both as low-lying bound states of the fundamental degrees of freedom of quantum chromodynamics as…
Effects of a dressed quark-gluon vertex in pseudoscalar heavy-light mesons
M. Gomez-Rocha, T. Hilger, A. Krassnigg
Using a simple model in the context of the Dyson-Schwinger-Bethe-Salpeter approach, we investigate the effects of a dressed-quark-gluon vertex on pseudoscalar meson masses. In part…
Strong three-meson couplings of and
Wolfgang Lucha, Dmitri Melikhov, Hagop Sazdjian +1
We discuss the strong couplings and for vector () and pseudoscalar () mesons, at least one of which is a charmonium state or . The strong coupl…
Asymptotic freedom in the front-form Hamiltonian for quantum chromodynamics of gluons
Maria Gomez-Rocha, Stanislaw D. Glazek
Asymptotic freedom of gluons in QCD is obtained in the leading terms of their renormalized Hamiltonian in the Fock space, instead of considering virtual Green's functions or scatte…
Accurate decay-constant ratios and from Borel QCD sum rules
Wolfgang Lucha, Dmitri Melikhov, Silvano Simula
We present our analysis of the decay constants of the beauty vector mesons and within the framework of dispersive sum rules for the two-point correlator of vector cur…
Dilepton constraints in the Inert Doublet Model from Run 1 of the LHC
G. Belanger, B. Dumont, A. Goudelis +3
Searches in final states with two leptons plus missing transverse energy, targeting supersymmetric particles or invisible decays of the Higgs boson, were performed during Run 1 of…
Vacuum energy and the cosmological constant
Steven D. Bass
The accelerating expansion of the Universe points to a small positive value for the cosmological constant or vacuum energy density. We discuss recent ideas that the cosmological co…
Masses of J^PC =1^-+ exotic quarkonia in a Bethe-Salpeter-equation approach
T. Hilger, M. Gomez-Rocha, A. Krassnigg
We investigate the properties of mesons with the exotic J^PC = 1^-+ quantum numbers. Starting out from the light-quark domain, where the π_1 states are used as references, we predi…
Constraints on sneutrino dark matter from LHC Run 1
Chiara Arina, Maria Eugenia Cabrera Catalan, Sabine Kraml +2
A mostly right-handed sneutrino as the lightest supersymmetric particle (LSP) is an interesting dark matter candidate, leading to LHC signatures which can be quite distinct from th…
Advances in QCD sum rule calculations
Dmitri Melikhov
We review the recent progress in the applications of QCD sum rules to hadron properties with the emphasis on the following selected problems: (i) development of new algorithms for…
Nucleosynthesis constraints on the faint vector portal
Anthony Fradette, Maxim Pospelov, Josef Pradler +1
New Abelian U(1)' gauge bosons can couple to the Standard Model through mixing of the associated field strength tensor with the one from hypercharge, . Her…
