Trapping penguins with entangled B mesons
Physics Letters B, 2016 The first direct observation of time-reversal (T) violation in the $B\bar{B}$ system has been reported by the BaBar collaboration, employing the method of Ba$\tilde {\rm n}\!$uls and Bernabéu. Given this, we generalize their analysis of the time-dependent T-violating asymmetry ($A_{T}$) to consider different choices of CP tags for which the dominant ...

Weak decays of $$B_c$$ Bc into two hadrons under flavor SU(3) symmetry
European Physical Journal C: Particles and Fields, 2018 A large number of $$B_c$$ Bc meson events have been recorded at the LHCb detector, especially some two-body hadronic decay modes. We analyzed the weak decays of the $$B_c$$ Bc meson into two hadron states under the flavor SU(3) symmetry.

Violation of a Bell inequality in particle physics experimentally verified?
, 2004 Relevant aspects for testing Bell inequalities with entangled meson-antimeson systems are analyzed. In particular, we argue that the result of A. Go, J. Mod. Optics 51, 991 (2004), which nicely illustrate the quantum entanglement of B-meson pairs, cannot

B-meson-quark coupling constant and decay width of B*-meson
Fizika B : a journal of experimental and theoretical physics, 1998 Određuju se konstante vezanja pion – kvark (gπqq) i B-mezon – kvark (gB−qq) u procesima B∗−→B−π0 i B∗−→B−γ. Njihove se širine raspada računaju preko izravnog vezanja π0 i B− s kvarkovima koji miruju u B∗− mezonu.

Exclusive radiative decays of B mesons [PDF]
Nuclear Physics B - Proceedings Supplements, 2003 We present within the Standard Model the exclusive radiative decays B -> K*/rho gamma and B_(s/d) -> gamma gamma in QCD factorization based on the heavy-quark limit m_b >> Lambda_QCD. For the decays with a vector meson in the final state we give results complete to next-to-leading order in QCD.

Rare B Meson Decays at the Tevatron
EPJ Web of Conferences, 2012 Rare B meson decays are an excellent probe for beyond the Standard Model physics. Two very sensitive processes are the b → sμ+μ− and Bs,d0 → μ+μ− decays. We report recent results at a center of mass energy of √s = 1.96 TeV from CDF II using 7 fb−1 at the

, 2011 Rare decays of the B-meson that arise due to loop-mediated FCNC transitions are known to provide important constraints on beyond-SM theories. Basic properties of several such decays are reviewed here.

, 2003 B meson semileptonic decays are a crucial tool in our studies of the quark mixing parameters Vcb and Vub. The interplay between experimental and theoretical challenges to achieve precision in the determination of these fundamental parameters is discussed.
