 Bounds on dark matter annihilations from 21cm data / D'Amico, Guido (CERN) The observation of an absorption feature in the 21 cm spectrum at redshift z ≈17 implies bounds on Dark Matter annihilations for a broad range of masses,given that significant heating of the intergalactic medium would have erasedsuch feature.

 Status of Lepton flavour universality and other discrepancies in $B$ physics / Straub, David M (Munich, Tech. U., Universe) Following the updated measurement of the lepton flavour universality (LFU) ratioRK in B → KK decays by LHCb, as well as a number of further measurements, e.g.RK * by Belle and Bs → μμ by ATLAS, I present an analysis of the global statusof new physics in b → s transitions in the weak effective theory at the b-quarkscale, in the Standard Model effective theory above the electroweak scale, andin simplified models of new physics.. 2019. - 10 p.
