It is proposed to exploit the decay of the meson ${B}^+ \rightarrow p \pi^+ \pi^+ \bar{\Sigma}_c^{--}$ and of its charge conjugate $B^-$ copiously produced at LHC to obtain a sample of $\Lambda_c$ baryons through the strong decay $\Sigma_c…

We analyze 230.4 fb-1 of data collected with the BaBar detector at the PEP-II e+ e- collider at SLAC to search for evidence of D0--anti-D0 mixing using regions of phase space in the decay D0 --> K+ pi- pi0. We measure the time-integrated…

Two bottom $\Sigma_b(6097)^\pm$ baryons were observed in the final states $\Lambda_b^0\pi^-$ and $\Lambda_b^0\pi^+$ in $pp$ collision by LHCb collaboration, whose masses and widths were measured. In a $^{3}P_{0}$ model, the strong decay…

We study the charmless baryonic three-body decays of B mesons: B+ to p Lambdabar gamma, B+ to p Lambdabar pi0 and B0 to p Lambdabar pi-. The partial branching fractions as a function of the baryon-antibaryon mass and the polar angle…

We calculate the shape of the $\pi\Sigma$ and $\bar K N$ invariant mass distributions in the $\Lambda_b \to J/\psi\, \pi\Sigma$ and $\Lambda_b \to J/\psi \,\bar K N$ decays that are dominated by the $\Lambda(1405)$ resonance. The weak…

We study for the first time the three-body charmless baryonic decays $\bar B^0_s\to \bar p \Lambda M^+ (p \bar \Lambda M^-)$, with $M=\pi, K$. We find that the branching ratios of $\bar B^0_s\to (\bar p \Lambda K^+$ and $p\bar \Lambda K^-)$…

The noteworthy BaBar and Belle evidence for $D^0$-$\bar{D}^0$ mixing motivates us to study its impact on $D^0\to K^{*\pm} K^\mp$ decays and their CP-conjugate processes. We show that both the $D^0$-$\bar{D}^0$ mixing parameters ($x$ and…

The $\Xi_c^0$ baryon is unstable and usually decays into charmless final states by the $c \to s u\overline{d}$ transition. It can, however, also disintegrate into a $\pi^-$ meson and a $\Lambda_c^+$ baryon via $s$ quark decay or via $cs\to…
