Measurement of CP Asymmetries and Branching Fractions in B to pi pi and B to K pi Decays.

, 2006
The authors present preliminary measurements of the Cp asymmetries and branching fractions for B {yields} {pi}{pi} and B {yields} K{pi} decays. A total of 347 million B{bar B} events collected by the BABAR detector at the PEP-II asymmetric-energy e{sup +}

Polarization and quantum entanglement effects in $$B^\pm _c\rightarrow J/\psi +\pi ^\pm +\pi ^0$$ B c ± → J / ψ + π ± + π 0 process

European Physical Journal C: Particles and Fields
Motivated by the very recent observation of the $$B^+_c\rightarrow J/\psi +\pi ^+ +\pi ^0$$ B c + → J / ψ + π + + π 0 decay using proton–proton collision data by the LHCb collaboration, we study the four-body angular distributions and the quantum ...

Antiretroviral Therapy with Ritonavir-Boosted Atazanavir- and Lopinavir-Containing Regimens Correlates with Diminished HIV-1 Neutralization

Vaccines
Background/Objectives: The impact of virion maturation on neutralizing antibody responses in HIV treatment is not fully understood. This study examines whether antiretroviral regimens (ART) with boosted protease inhibitors (b-PI), which increase exposure

Search for the B c + $$ {B}_c^{+} $$ → χ c1(3872)π + decay

Journal of High Energy Physics
A search for the decay B c + $$ {B}_c^{+} $$ → χ c1(3872)π + is reported using proton-proton collision data collected with the LHCb detector between 2011 and 2018 at centre-of-mass energies of 7, 8, and 13 TeV, corresponding to an integrated luminosity ...

Measurement of the Ratios of Branching Fractions B(Bs->Ds- pi+)/B(B0->D-pi+) and B(B+->D0bar pi+)/B(B0->D-pi+)

, 2005
We report an observation of the decay Bs -> Ds- pi+ in p pbar collisions at sqrt(s) = 1.96 TeV using 115 pb^(-1) of data collected by the CDF II detector at the Fermilab Tevatron. We observe 83 +/- 11 Bs -> Ds- pi+ candidates, representing a large increase in statistics over previous measurements and the first observation of this decay at a p pbar ...

Hunting for the alpha: $B\to \rho\rho$, $B \to \pi\pi$, $B \to\pi\rho$

, 2005
The hypothesis of the smallness of penguin contribution to charmless strangeless $B_d (\bar B_d)$ decays allows to determine with high accuracy the value of angle $\alpha$ from the currently available $B \to \rho\rho$, $B \to \pi\pi$ and $B\to \rho\pi$ decay data.

B -> pi, B(s) -> K form factors and Vub determination

, 2008
We present a QCD light-cone sum rule (LCSR) estimation of the B -> pi, B -> K, and Bs -> K form factors calculating gluon radiative corrections at next-to-leading order. The MS-bar b-quark mass is used, instead of the one-loop pole mass employed in the previous analyses.

The “ $$B\rightarrow K\pi $$ B → K π puzzle”: a new perspective

European Physical Journal C: Particles and Fields
A phenomenological analysis based on the published branching fractions and CP asymmetry observables of the $$B\rightarrow K\pi $$ B → K π , $$B\rightarrow \pi \pi $$ B → π π and $$B\rightarrow KK$$ B → K K dataset is performed.
