TLDR
In this article, an angular analysis and a measurement of the differential branching fraction of the decay B0s→ϕμ+μ− are presented, using data corresponding to an integrated luminosity of 3.0fb−1 of pp collisions recorded by the LHCb experiment at s√=7 and 8TeV.
Abstract
An angular analysis and a measurement of the differential branching fraction of the decay B0s→ϕμ+μ− are presented, using data corresponding to an integrated luminosity of 3.0fb−1 of pp collisions recorded by the LHCb experiment at s√=7 and 8TeV. Measurements are reported as a function of q2, the square of the dimuon invariant mass and results of the angular analysis are found to be consistent with the Standard Model. In the range 1<q2<6GeV2/c4, where precise theoretical calculations are available, the differential branching fraction is found to be 3.5σ below the Standard Model predictions.

B-decay discrepancies after Moriond 2019

TL;DR: In this article, the authors analyse the global status of new physics in b-quark and b-s transitions in the weak effective theory at the bquark scale, in the Standard Model effective theory in the electroweak scale, and in simplified models of the new physics.

Minimal Explanation of Flavor Anomalies: B-Meson Decays, Muon Magnetic Moment, and the Cabibbo Angle.

TL;DR: In this article, the authors proposed a coherent pattern of new physics effects induced by two scalar mediators, a leptoquark S 1 and a charged singlet ϕ^{+}.

Inelastic extra U(1) charged scalar dark matter

TL;DR: In this paper, the authors show that the present scalar dark matter (DM) annihilation cross section to bottom quark pairs through the Higgs boson exchange is smaller than about 10 − 10 − 31 − 3 for a wide DM mass range, which is much smaller than the required annihilation cross-section for thermal relic DM.

A Decision-Theoretic Generalization of On-Line Learning and an Application to Boosting

TL;DR: The model studied can be interpreted as a broad, abstract extension of the well-studied on-line prediction model to a general decision-theoretic setting, and it is shown that the multiplicative weight-update Littlestone?Warmuth rule can be adapted to this model, yielding bounds that are slightly weaker in some cases, but applicable to a considerably more general class of learning problems.
