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

open access: yes, 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.

Study of four-body decays $$B_{(s)} \rightarrow (\pi \pi )(\pi \pi )$$ B ( s ) → ( π π ) ( π π ) in the perturbative QCD approach

open access: yesEuropean Physical Journal C: Particles and Fields, 2023
In this work, we make a systematical study on the four-body $$B_{(s)} \rightarrow (\pi \pi )(\pi \pi )$$ B ( s ) → ( π π ) ( π π ) decays in the perturbative QCD (PQCD) approach, where the $$\pi \pi $$ π π invariant mass spectra are dominated by the ...

Observation of a broad structure in the pi+ pi- J/psi mass spectrum around 4.26 GeV/c2. [PDF]

open access: yesPhysical Review Letters, 2005
We study initial-state radiation events, e+ e- --> gammaISR pi+ pi- J/psi, with data collected with the BABAR detector. We observe an accumulation of events near 4.26 GeV/c2 in the invariant-mass spectrum of pi+ pi- J/psi.

Observation of Λ b 0 $$ {\Lambda}_b^0 $$ → D + pπ − π − and Λ b 0 $$ {\Lambda}_b^0 $$ → D *+ pπ − π − decays

open access: yesJournal of High Energy Physics, 2022
The multihadron decays Λ b 0 $$ {\Lambda}_b^0 $$ → D+pπ−π− and Λ b 0 $$ {\Lambda}_b^0 $$ → D *+pπ−π− are observed in data corresponding to an integrated luminosity of 3 fb −1, collected in proton-proton collisions at centre-of-mass energies of 7 and 8 ...

A search for $\it{\Xi}^{++}_{cc} \rightarrow D^{+} p K^{-} \pi^{+}$ decays [PDF]

open access: yes, 2019
A search for the $\it{\Xi}^{++}_{cc}$ baryon through the $\it{\Xi}^{++}_{cc} \rightarrow D^{+} p K^{-} \pi^{+}$ decay is performed with a data sample corresponding to an integrated luminosity of 1.7 $\mathrm{fb}^{-1}$ recorded by the LHCb experiment in ...

Search for CP violation in $D^{\pm}\rightarrow K^0_{\mathrm{S}} K^{\pm}$ and $D^{\pm}_{s}\rightarrow K^0_{\mathrm{S}} \pi^{\pm}$ decays [PDF]

open access: yes, 2014
A search for \CP violation in Cabibbo-suppressed $D^{\pm}\rightarrow K^0_{\mathrm{S}} K^{\pm}$ and $D^{\pm}_{s}\rightarrow K^0_{\mathrm{S}} \pi^{\pm}$ decays is performed using $pp$ collision data, corresponding to an integrated luminosity of 3~fb$^{-1}$,

Charmless B Decays to Final States with Radially Excited Vector Mesons [PDF]

open access: yes, 2002
We consider the weak decays of a B meson to final states that contain a S-wave radially excited vector meson. We consider vector-pseudoscalar final states and calculate ratios of the type $B \to \rho^{\prime} \pi/B \to \rho \pi$, $B \to \omega^{\prime ...
