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.

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.

CP Violation and Rare Kaon Decays [PDF]

, 1999
We summarize both the study of CP violation with $K$ and $B$ mesons, as well as rare decays of kaons, emphasizing recent developments. The topics discussed include the unitarity triangle, $\epsilon'/\epsilon$, $K\to\pi\nu\bar\nu$ and other rare $K ...

Are the anti-charmed and bottomed pentaquarks molecular heptaquarks?

, 2004
I study the charmed $uudd\bar c$ resonance D*p (3100) very recently discovered by the H1 collaboration at Hera. An anticharmed resonance was already predicted, in a recent publication mostly dedicated to the S=1 resonance Theta+(1540).

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.

Study of CP violations in $$B^-\rightarrow K^- \pi ^+\pi ^-$$ B-→K-π+π- and $$B^-\rightarrow K^- f_0(500)$$ B-→K-f0(500) decays in the QCD factorization approach

European Physical Journal C: Particles and Fields, 2018
Within the QCD factorization approach, we study the CP violations in $$B^-\rightarrow K^-\pi ^+\pi ^-$$ B-→K-π+π- and $$B^-\rightarrow K^- f_0(500)$$ B-→K-f0(500) decays. We find the experimental data of the localized CP asymmetry in $$B^-\rightarrow K^-\

Charmed Baryonium

, 2010
We re-analyze the published data on the Y(4630) --> Lambda_c Lambdabar_c and the Y(4660) --> psi(2S) pi pi with a consistent Ansatz and we find that the two observations are likely to be due to the same state Y_B with M_{Y_B} = 4660.7 +- 8.7 MeV and ...

The decays of $$\bar{B}^0$$ B¯0 , $$\bar{B}^0_s$$ B¯s0 and $$B^-$$ B- into $$\eta _c$$ ηc plus a scalar or vector meson

European Physical Journal C: Particles and Fields, 2018
We investigate the decays of $$\bar{B}^0_s$$ B¯s0 , $$\bar{B}^0$$ B¯0 and $$B^-$$ B- into $$\eta _c$$ ηc plus a scalar or vector meson in a theoretical framework by taking into account the dominant process for the weak decay of $$\bar{B}$$ B¯ meson into $

Resonance model study of strangeness production in pp collisions [PDF]

, 1996
Results for the energy dependence of the elementary kaon production cross sections in proton-proton collisions are reported. Calculations are performed within an extended version of the resonance model which was used for the previous studies of ...
