Precision measurement of CP violation and branching fractions in $B^{\pm} \to K^0_{\mathrm{S}} h^{\pm}$ $(h = \pi, K)$ decays and search for the rare decay $B_c^{\pm} \to K ^0_{\mathrm{S}} K^{\pm}$
An analysis of the decays $B^{\pm} \to K^0_{\mathrm{S}} \pi^{\pm}$ and $B^{\pm} \to K^0_{\mathrm{S}} K^{\pm}$ is performed using proton-proton collision data collected by the LHCb experiment at a center-of-mass energy of $13 TeV$, corresponding to an integrated luminosity of 5.4fb$^{-1}$. [...]

Axion couplings in Orbifold GUTs / Agrawal, Prateek (UC, Santa Barbara ; Oxford U., Theor. Phys.) ; Nee, Michael (Harvard U.) ; Reig, Mario (U. Oxford (main) ; CERN)
We consider the coupling of axions to gauge bosons in higher-dimensional Grand Unified Theories (GUT) inspired by string theory constructions with D-branes on orbifold singularities, the so-called orbifold GUTs. [...]
