The possible $$B\pi $$ B π molecular state and its radiative decay

European Physical Journal C: Particles and Fields, 2017
Recently, several exotic bosons have been confirmed as multi-quark states. However, there are violent disputes about their inner structures, namely if they are molecular states or tetraquarks, or even mixtures of the two structures.

Dalitz Plot Analysis of B- ---> D+ pi- pi- [PDF]

, 2009
We report on a Dalitz plot analysis of B- -> D+pi(-)pi(-) decays, based on a sample of about 383 x 10(6) Y(4S) -> B (B) over bar decays collected with the BABAR detector at the PEP-II asymmetric-energy B Factory at SLAC.

Di-Pion Decays of Heavy Quarkonium in the Field Correlator Method

, 2007
Mechanism of di-pion transitions $nS\to n'S\pi\pi(n=3,2; n'=2,1)$ in bottomonium and charmonium is studied with the use of the chiral string-breaking Lagrangian allowing for the emission of any number of $\pi(K,\eta),$ and not containing fitting ...

An intracellular transporter mitigates the CO2‐induced decline in iron content in Arabidopsis shoots

FEBS Letters, EarlyView.
This study identifies a gene encoding a transmembrane protein, MIC, which contributes to the reduction of shoot Fe content observed in plants under elevated CO2. MIC is a putative Fe transporter localized to the Golgi and endosomal compartments. Its post‐translational regulation in roots may represent a potential target for improving plant nutrition ...

Measurement of the ratio of branching fractions B B c + → B s 0 π + / B B c + → J / ψ π + $$ \mathcal{B}\left({B}_c^{+}\to {B}_s^0{\pi}^{+}\right)/\mathcal{B}\left({B}_c^{+}\to J/\psi {\pi}^{+}\right) $$

Journal of High Energy Physics, 2023
The ratio of branching fractions of B c + → B s 0 π + $$ {B}_c^{+}\to {B}_s^0{\pi}^{+} $$ and B c + → J / ψ π + $$ {B}_c^{+}\to J/\psi {\pi}^{+} $$ decays is measured with proton-proton collision data of a centre-of-mass energy of 13 TeV.

Direct CP Violation, Branching Ratios and Form Factors $B \to \pi$, $B \to K$ in $B$ Decays

, 2004
The $B \to \pi$ and $B \to K$ transitions involved in hadronic B decays are investigated in a phenomenological way through the framework of QCD factorization.

Penguin decays of B mesons [PDF]

, 1998
Penguin, or loop, decays of B mesons induce effective flavor-changing neutral currents, which are forbidden at tree level in the Standard Model. These decays give special insight into the CKM matrix and are sensitive to non-standard model effects.

Phosphatidylinositol 4‐kinase as a target of pathogens—friend or foe?

FEBS Letters, EarlyView.
This graphical summary illustrates the roles of phosphatidylinositol 4‐kinases (PI4Ks). PI4Ks regulate key cellular processes and can be hijacked by pathogens, such as viruses, bacteria and parasites, to support their intracellular replication. Their dual role as essential host enzymes and pathogen cofactors makes them promising drug targets.

Strong D* -> D pi and B* -> B pi couplings [PDF]

, 2010
We compute g(D*D pi) and g(B*B pi) using a framework in which all elements are constrained by Dyson-Schwinger equation studies of QCD and therefore incorporates a consistent, direct, and simultaneous description of light and heavy quarks and the states ...

Wrinkling of a bilayer membrane [PDF]

, 2006
The buckling of elastic bodies is a common phenomenon in the mechanics of solids. Wrinkling of membranes can often be interpreted as buckling under constraints that prohibit large amplitude deformation.
