DO-TH 17/04 RK and RK∗ beyond the Standard Model
RK and RK∗ beyond the Standard Model Gudrun Hiller ∗ and Ivan Nǐsandžić † Institut für Physik, Technische Universität Dortmund, D-44221 Dortmund, Germany Measurements of the ratio of B → K∗μμ to B → K∗ee branching fractions, RK∗ , by the LHCb collaboration strengthen the hints from previous studies with pseudoscalar kaons, RK , for the breakdown of lepton universality, and therefore the Standar...
متن کاملImplications of the RK and RK∗ anomalies
We discuss the implications of the recently reported RK and RK∗ anomalies, the lepton flavor non-universality in the B → Kll and B → Kll. Using two sets of hadronic inputs of form factors, we perform a fit of the new physics to the RK and RK∗ data, and significant new physics contributions are found. We propose to study the lepton flavor universality in a number of related rare B,Bs, Bc and Λb ...
متن کاملSterile neutrinos and RK
We consider an enhancement in the violation of lepton flavour universality in light meson decays arising from modified Wlν couplings in the standard model minimally extended by sterile neutrinos. Due to the presence of additional mixings between the active neutrinos and the new sterile states, the deviation from unitarity of the leptonic mixing matrix intervening in charged currents might lead ...
متن کاملA Minimal Rk-degree
We construct a minimal rK-degree, continuum many, in fact. We also show that every minimal sequence, that is, a sequence with minimal rK-degree, must have very low descriptional complexity, that every minimal sequence is rK-reducible to a random sequence, and that there is a random sequence with no minimal sequence rK-reducible to it.

The present study includes 50 patients symptomatic for tuberculous meningitis and 15 patients with meningitis other than tuberculosis The CSF specimens were subjected for ADA titer estimation, AFB smear preparation and molecular characterization by Nested-PCR for IS6110 gene. Out of 50 specimens 2 came AFB smear positive whereas 29 specimens came positive for Tuberculosis (TB) PCR and 21were ne...
