Unified study of $$B_s^0 \rightarrow X(3872) \pi ^+\pi ^- (K^+ K^-)$$ B s 0 → X ( 3872 ) π + π - ( K + K - ) and $$B_s^0 \rightarrow \psi (2S) \pi ^+\pi ^- (K^+ K^-)$$ B s 0 → ψ ( 2 S ) π + π - ( K + K - ) processes

open access: yesEuropean Physical Journal C: Particles and Fields
We perform a unified description of the experimental data of the $$\pi ^+\pi ^-$$ π + π - invariant mass spectra of $$B_s^0 \rightarrow \psi (2S) \pi ^+\pi ^-$$ B s 0 → ψ ( 2 S ) π + π - , the $$\pi ^+\pi ^-$$ π + π - and $$K^+ K^-$$ K + K - invariant ...

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

open access: yesEuropean 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.

Study of the rare B-s(0) and B-0 decays into the pi(+) pi(-) mu(+) mu(-) final state

open access: yes, 2015
A search for the rare decays B-s(0) -> pi(+) pi-mu(+) mu-and B-0 -> pi(+) pi-mu(+) mu-is performed in a data set corresponding to an integrated luminosity of 3.0 fb(-1) collected by the LHCb detector in proton-proton collisions at centre-of-mass energies

Measurement of the B^0 -> D^*- pi^+ pi^- pi^+ branching fraction [PDF]

open access: yes, 2016
See paper for full list of authors, 7 pages, 3 postscript figures, submitted to PRD-RCInternational audienceUsing a sample of (470.9 +- 2.8) x 10^6 BB-bar pairs, we measure the decay branching fraction B(B^0 -> D^*- pi^+ pi^- pi^+) = (7.26 +- 0.11 +- 0 ...

Charmed $$\Omega _c$$ Ω c weak decays into $$\Omega $$ Ω in the light-front quark model

open access: yesEuropean Physical Journal C: Particles and Fields, 2020
More than ten $$\Omega _c^0$$ Ω c 0 weak decay modes have been measured with the branching fractions relative to that of $$\Omega ^0_c\rightarrow \Omega ^-\pi ^+$$ Ω c 0 → Ω - π + .

First measurements of eta(c) decaying into K (+) K (-)2 (pi(+)pi(-)) and 3(pi(+)pi(-))

open access: yes, 2006
The decays of eta(c) to K(+)K(-)2(pi(+)pi(-)) and 3(pi(+)pi(-)) are observed for the first time using a sample of 5.8 x 10(7) J/psi events collected by the BESII detector.

Study of B ->rho pi decays at Belle

open access: yes, 2002
This Letter describes a study of B meson decays to the pseudoscalar-vector final state rhopi using 31.9 x 106 BB events collected with the Belle detector at KEKB. The branching fractions B(B+ --> rho(0)pi(+)) = (8.0(-2.0-0.7)(+2.3+0.7)) X 10(-6) and B(
