A study of the dynamics rare decay K±→π±γγ has been performed on a sample 232 candidates, with an estimated background 17.4±1.1 events, collected by NA62 experiment at CERN in 2007. The results are combined those from measurement conducted NA48/2 Collaboration CERN. model-independent branching ratio kinematic range z=(mγγ/mK)2>0.2 is BMI(z>0.2)=(0.965±0.063)×10−6, and full assuming Chiral Perturbation Theory description B(Kπγγ)=(1.003±0.056)×10−6. detailed comparison previous measurements performed.
The NA62 experiment collected a large sample of charged kaon decays in 2007 with highly efficient trigger for into electrons. A measurement the $\pi^0$ electromagnetic transition form factor slope parameter from $1.11\times10^{6}$ fully reconstructed $K^\pm \to \pi^\pm \pi^0_D, \pi^0_D e^+ e^-\gamma$ events is reported. measured value $a = (3.68 \pm 0.57)\times10^{-2}$ good agreement theoretical expectations and previous measurements, represents most precise experimental determination...
Using 13.7fb−1 of data recorded by the CLEO detector at Cornell Electron Storage Ring, we report evidence two new charmed baryons: one decaying into Ξc0′π+ with subsequent decay Ξc0′→Ξc0γ, and its isospin partner Ξc+′π− followed Ξc+′→Ξc+γ. We measure following mass differences for states: M(Ξc0γπ+)−M(Ξc0)=318.2±1.3±2.9MeV M(Ξc+γπ−)−M(Ξc+)=324.0±1.3±3.0MeV. interpret these states as JP=12− Ξc1 particles, charmed-strange analogs Λc1+(2593).Received 7 December...
We have measured the charge asymmetry in like-sign dilepton yields from B(0)B*(0) meson decays using CLEO detector at Cornell Electron Storage Ring. find a(0)(ll) identical with[N(l(+)l(+))-N(l(-)l(-))]/[N(l(+)l(+))+N(l(-)l(-))] = +0.013+/-0.050+/-0.005. combine this result with a previous, independent measurement and obtain Re(epsilon(B))/(1+ absolute value of epsilon(B)(2)) +0.0035+/-0.0103+/-0.0015 (uncertainties are statistical systematic, respectively) for CP impurity parameter, epsilon(B).
We present preliminary data which demonstrate that the ${\ensuremath{\pi}}^{\ensuremath{-}}p$ charge-exchange differential cross section at 180\ifmmode^\circ\else\textdegree\fi{} in momentum region between 1.8 and 5.0 BeV/c is quite similar shape to elastic ${\ensuremath{\pi}}^{\ifmmode\pm\else\textpm\fi{}}$ sections 180\ifmmode^\circ\else\textdegree\fi{}.
The CLEO experiment at the CESR collider has used 13.7 fb$^{-1}$ of data to search for production $\Omega_c^0$ (css-ground state) in $e^{+}e^{-}$ collisions $\sqrt{s} \simeq 10.6$ {\rm GeV}. modes study are $\Omega^- \pi^+$, \pi^+ \pi^0$, $\Xi^- K^- pi^+ $\Xi^0 pi^+$, and \pi^- \pi^+$. We observe a signal 40.4$\pm$9.0(stat) events mass 2694.6$\pm$2.6(stat)$\pm$1.9(syst) MeV/$c^2$}, all combined.
We report on a search for supersymmetric $\tilde{B}$ meson with mass between 3.5 and 4.5 GeV/$c^2$ using 4.52 ${\rm fb}^{-1}$ of integrated luminosity produced at $\sqrt{s}=10.52$ GeV, just below the $e^+e^-\to B\bar{B}$ threshold, collected CLEO detector. find no evidence light scalar bottom quark.

The differential cross sections for ${\ensuremath{\pi}}^{\ensuremath{-}}p$ charge exchange at 180\ifmmode^\circ\else\textdegree\fi{} are given as a function of ${\ensuremath{\pi}}^{\ensuremath{-}}$ momentum from 1.8 to $6.0 \frac{\mathrm{GeV}}{c}$. Below $4 \frac{\mathrm{GeV}}{c}$ there is resonancelike structure. Above the data in excellent agreement with smooth exponential drop. A modification Igi model gives good fit data. dependence moduli isospin-\textonehalf{} and $\frac{3}{2}$...
