High Quality Axion in Supersymmetric Models / Choi, Gongjun ; Yanagida, Tsutomu T.
In this work, we discuss how the use of the symmetries well motivated in physics beyond the Standard model (BSM) can guarantee the high quality axions. [...]

New Sum Rules for the $B_c \to J/\psi$ Form Factors / Bordone, Marzia (CERN) ; Khodjamirian, Alexander (Siegen U.) ; Mannel, Thomas
We derive new sum rules for the form factors of the $B_c\to J/\psi\, \ell \bar{\nu}_\ell$ semileptonic transitions, employing the vacuum-to-$B_c$ correlation function of the $J/\psi$-interpolating and $b\to c$ weak currents. [...]

No room to hide: implications of cosmic-ray upscattering for GeV-scale dark matter / Alvey, James (U. Amsterdam, GRAPPA) ; Bringmann, Torsten (Oslo U. ; CERN) ; Kolesova, Helena (Stavanger U.)
The irreducible upscattering of cold dark matter by cosmic rays opens up the intriguing possibility of detecting even light dark matter in conventional direct detection experiments or underground neutrino detectors. [...]

Charting the Higgs self-coupling boundaries / Durieux, Gauthier (CERN) ; McCullough, Matthew (CERN) ; Salvioni, Ennio (Padua U. ; INFN, Padua)
Could new physics first manifest itself in Higgs self-coupling measurements? In other words, how large could deviations in the Higgs self-coupling be, if other Higgs and electroweak measurements are compatible with Standard Model predictions? Using theoretical arguments supported by concrete models we derive a bound on the ratio of self-coupling to single-Higgs coupling deviations in ultraviolet completions of the Standard Model where parameters are not fine-tuned.
