أجريت بحثاً عن الانحلال النادر $B^0 rightarrow J/psi phi$ باستخدام بيانات تصادمات $pp$ التي تم جمعها بمتكامل الطاقة الحرارية للمحطة LHCb في الطاقات 7، 8 و 13 تيف، مما يعادل الضوء المتراكم 9 ${rm fb}^{-1}$. لم يتم الكشف عن إشارة معنوية للانحلال و تم ضبط حد على الفرعية التشعبية بقيمة $1.1 times 10^{-7}$ بدرجة اعتماد 90٪.
A search for the rare decay $B^0 rightarrow J/psi phi$ is performed using $pp$ collision data collected with the LHCb detector at centre-of-mass energies of 7, 8 and 13 TeV, corresponding to an integrated luminosity of 9 ${rm fb}^{-1}$. No significant signal of the decay is observed and an upper limit of $1.1 times 10^{-7}$ at 90% confidence level is set on the branching fraction.

The $B_s^0 rightarrow J/psi phi phi$ 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 $B_s^0$ meson is measured to be $5367.08,pm ,0.38,pm, 0.15$ MeV/c$^2$. The branching fraction ratio $mathcal{B}(B_s^0 rightarrow J/psi phi phi)/mathcal{B}(B_s^0 rightarrow J/psi phi)$ 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 $B_s^0 rightarrow J/psi phi K^+ K^-$ or $B_s^0 rightarrow J/psi K^+ K^- K^+ K^-$ decays is found.
Using a data sample of $448.1times10^6$ $psi(3686)$ events collected at $sqrt{s}=$ 3.686 GeV with the BESIII detector at the BEPCII, we search for the rare decay $J/psi to phi e^+ e^-$ via $psi(3686) to pi^+pi^- J/psi $. No signal events are observed
and the upper limit on the branching fraction is set to be $mathcal{B}(J/psi to phi e^+ e^-) < 1.2 times 10^{-7}$ at the 90% confidence level, which is still about one order of magnitude higher than the Standard Model prediction.
A search for the rare decay of a $B^{0}$ or $B^{0}_{s}$ meson into the final state $J/psigamma$ is performed, using data collected by the LHCb experiment in $pp$ collisions at $sqrt{s}=7$ and $8$ TeV, corresponding to an integrated luminosity of 3 fb
$^{-1}$. The observed number of signal candidates is consistent with a background-only hypothesis. Branching fraction values larger than $1.7times 10^{-6}$ for the $B^{0}to J/psigamma$ decay mode are excluded at 90% confidence level. For the $B^{0}_{s}to J/psigamma$ decay mode, branching fraction values larger than $7.4times 10^{-6}$ are excluded at 90% confidence level, this is the first branching fraction limit for this decay.
One of the most intriguing puzzles in hadron spectroscopy are the numerous charmonium-like states observed in the last decade, including charged states that are manifestly exotic. Over the years, the experiment $BABAR$ has extensively studied those i
n B meson decays, initial state radiation processes and two photon reactions. We report in this paper a new study on some of those states, performed using the entire data sample collected by $BABAR$ in $e^+e^-$ collisions, at center of mass energies near 10.58 GeV/c$^2$. The study of the process $B rightarrow J/psi phi K$ will be presented, and the search for the resonant states X(4140) and X(4270) in their decays to $J/psi phi$, will be highlighted.
Using a sample of $1.31$ billion $J/psi$ events accumulated with the BESIII detector at the BEPCII collider, we report the observation of the decay $J/psi rightarrow phipi^{0}$, which is the first evidence for a doubly Okubo-Zweig-Iizuka suppressed e
lectromagnetic $J/psi$ decay. A clear structure is observed in the $K^{+} K^{-}$ mass spectrum around 1.02 GeV/$c^2$, which can be attributed to interference between $J/psi rightarrow phipi^{0}$ and $J/psi rightarrow K^{+}K^{-}pi^{0}$ decays. Due to this interference, two possible solutions are found. The corresponding measured values of the branching fraction of $J/psi to phipi^{0}$ are $[2.94 pm 0.16text{(stat.)} pm 0.16text{(syst.)}] times 10^{-6}$ and $[1.24 pm 0.33text{(stat.)} pm 0.30text{(syst.)}] times 10^{-7}$.
