The authors study the decay B[sup -] [yields] J/[psi]K[sup -][pi][sup +][pi][sup -] using 117 million B[bar B] events collected at the [Upsilon](4S) resonance with the BaBar detector at the PEP-II e[sup +]e[sup -] asymmetric-energy storage ring. They measure the branching fractions [Beta](B[sup -] [yields] J/[psi]K[sup -] [pi][sup +][pi][sup -]) = (116 [+-] 7(stat.) [+-] 9(syst.)) x 10[sup -5] and [Beta](B[sup -] [yields] X(3872)K[sup -]) x [Beta](X(3872) [yields] J/[psi][pi][sup +][pi][sup -]) = (1.28 [+-] 0.41) x 10[sup -5] and find the mass of the X(3872) to be 3873.4 [+-] 1.4MeV/c[sup 2]. They search for the h[sub c] narrow state in the decay B[sup -] [yields] h[sub c] K[sup -], h[sub c] [yields] J/[psi][pi][sup +][pi][sup -] and for the decay B[sup -] [yields] J/[psi]D[sup 0][pi][sup -], with D[sup 0] [yields] K[sup -][pi][sup +]. They set the 90% C.L. limits [Beta](B[sup -] [yields] h[sub c]K[sup -]) x [Beta](h[sub c] [yields] J/[psi][pi][sup +][pi][sup -])

We present results of a search for the X(3872) in B° → X(3872)K{sub S}°, X(3872) → J/???−, improved measurements of B− → X(3872)K−, and a study of the J/??+?− mass region above the X(3872). We use 232 million B{bar B} pairs collected at the?(4S) resonance with the BABAR detector at the PEP-II e+e− asymmetric-energy storage rings. The results include the 90% confidence interval 1.34 x 10−6

The decays B+c → J/[Psi]D+s and B+c → J/[Psi]D*s+ are studied with the ATLAS detector at the LHC using a dataset corresponding to integrated luminosities of 4.9 and 20.6 fb-1 of pp collisions collected at centre-of-mass energies √s = 7 TeV and 8 TeV, respectively. Furthermore, signal candidates are identified through J/[psi] → [mu]+[mu]- and D(*)+s → [Phi][pi]+([gamma]/[pi]0) decays.

We have studied the B{sup ±} → J/[psi][pi]{sup ±} and B{sup ±} → J/[psi] K{sup ±} decays using a 20.7 fb−1 data set collected with the BABAR detector. We observe a signal of 51 ± 10 B{sup ±} → J/[psi][pi]{sup ±} events and determine the ratio [Beta](B{sup {+-}} → J/[psi][pi]{sup {+-}})/[Beta](B{sup {+-}} → J/[psi] K{sup {+-}}) to be [3.91 {+-} 0.78(stat.) {+-} 0.19(syst.)]%. The CP-violating charge asymmetries for the B{sup {+-}} → J/[psi] [pi]{sup {+-}} and B{sup {+-}} → J/[psi] K{sup {+-}} decays are determined to be [Alpha]{sub {pi}} = 0.01 {+-} 0.22(stat.) {+-} 0.01(syst.) and [Alpha]{sub K} = 0.003 {+-} 0.030(stat.) {+-} 0.004(syst.).
