The Bs0​→J/ψϕϕ decay is observed in pp collision
data corresponding to an integrated luminosity of 3 fb−1 recorded by the
LHCb detector at centre-of-mass energies of 7 TeV and 8 TeV. This is the first
observation of this decay channel, with a statistical significance of 15
standard deviations. The mass of the Bs0​ meson is measured to be
5367.08±0.38±0.15 MeV/c2. The branching fraction ratio
B(Bs0​→J/ψϕϕ)/B(Bs0​→J/ψϕ) is measured to be 0.0115\,\pm\, 0.0012\, ^{+0.0005}_{-0.0009}.
In both cases, the first uncertainty is statistical and the second is
systematic. No evidence for non-resonant Bs0​→J/ψϕK+K− or Bs0​→J/ψK+K−K+K− decays is found.Comment: All figures and tables, along with any supplementary material and
additional information, are available at

The Bs 0 → J/ψϕϕ decay is observed in pp collision data corresponding to an integrated luminosity of 3 fb−1 recorded by the LHCb detector at centre-of-mass energies of 7 TeV and 8 TeV. This is the first observation of this decay channel, with a statistical significance of 15 standard deviations. The mass of the Bs 0 meson is measured to be 5367.08 ± 0.38 ± 0.15 MeV/c2. The branching fraction ratio ℬ(Bs 0 → J/ψϕϕ)/ℬ(Bs 0 → J/ψϕ) is measured to be 0.0115 ± 0.0012− 0.0009 + 0.0005. In both cases, the first uncertainty is statistical and the second is systematic. No evidence for non-resonant Bs 0 → J/ψϕK+K− or Bs 0 → J/ψK+K−K+K− decays is found

The product of the A(b)(0) ((B) over bar (0)) differential production
cross-section and the branching fraction of the decay A(b)(0)-> J/psi
pK(-) ((B) over bar (0)-> J/psi p (K) over bar*(892)(0)) is measured
as a function of the beauty hadron transverse momentum, p(T), and
rapidity, y. The kinematic region of the measurements is p(T) <20 GeV/c
and 2.0 < y < 4.5. The measurements use a data sample corresponding to
an integrated luminosity of 3fb(-1) collected by the LHCb detector in pp
collisions at centre-of-mass energies root s=7 TeV in 2011 and root s=8
TeV in 2012. Based on previous LHCb results of the fragmentation
fraction ratio, f(Ab0)/f(d), the branching fraction of the decay
A(b)(0)-> J/psi pK(-) is measured to be
B(A(b)(0)-> J/psi pK(-))=(3.17 +/- 0.04 +/- 0.07 +/-
0.34(-0.28)(+0.45))x10(-4)
where the first uncertainty is statistical, the second is systematic,
the third is due to the uncertainty on the branching fraction of the
decay (B) over bar (0)-> J/psi p (K) over bar*(892)(0), and the fourth
is due to the knowledge of f(Ab0)/f(d). The sum of the asymmetries in
the production and decay between A(b)(0) and (A) over bar (0)(b) is also
measured as a function of p(T) and y. The previously published branching
fraction of A(b)(0)-> J/psi p pi(-), relative to that of A(b)(0)-> J/psi
pK(-), is updated. The branching fractions of A(b)(0)-> P-c(+)(-> J/psi
p)K- are determined
