The decays B→Ψ(2S)π(K),ηc(2S)π(K) in the pQCD approach beyond the leading-order

Physics Letters B, 2017
Two body B meson decays involving the radially excited meson ψ(2S)/ηc(2S) in the final states are studied by using the perturbative QCD (pQCD) approach. We find that: (a) The branching ratios for the decays involving a K meson are predicted as Br(B+→ψ(2S)

Search for B -> h(*) nu nubar Decays at Belle

, 2007
We present a search for the rare decays B -> h(*) nu nubar, where h(*) stands for a light meson. A data sample of 535 million BBbar pairs collected with the Belle detector at the KEKB e+e- collider is used.

Lepto-quark portal dark matter

Journal of High Energy Physics, 2018
We consider the extension of the Standard Model with scalar leptoquarks as a portal to dark matter (DM), motivated by the recent anomalies in semi-leptonic B-meson decays. Taking singlet and triplet scalar leptoquarks as the best scenarios for explaining

Rare four-leptonic B-decays with light leptons in the final state in the Standard Model

EPJ Web of Conferences, 2017
We present predictions for the four-leptonic decays of B−-mesons with three light charged leptons and one neutrino in the final states. We obtain the branching ratio for B − → μ + μ − e − v ¯ e decay at the level 1.3 × 10−7 taking into

Constraining inverse moment of B-meson distribution amplitude using Lattice QCD data

Physics Letters B
We constrain the inverse moment of the B-meson light-cone distribution amplitude (LCDA), λB in heavy quark effective theory, using form factor estimates from Lattice QCD collaboration.

Cabibbo–Kobayashi–Maskawa-favored B decays to a scalar meson and a D meson

European Physical Journal C: Particles and Fields, 2017
In this work, we attempt to study the Cabibbo–Kobayashi–Maskawa-favored $$B \rightarrow \overline{D} S$$ B → D ¯ S (“S” denoting the scalar meson) decays within the perturbative QCD approach at the leading order and the leading power.

CP Violating Contribution to Delta Gamma in the B_s System from Mixing with a Hidden Pseudoscalar

, 2010
Recent evidence for a CP violating asymmetry in the semileptonic decays of B_s mesons cannot be accommodated within the Standard Model. Such an asymmetry can be explained by new physics contributions to Delta B=2 components of either the mass matrix or ...
