The flavour changing neutral current decay b→sγ has been detected in hadronic Z decays collected by ALEPH at LEP. signal is isolated lifetime-tagged bb̄ events the presence of a hard photon associated with system high momentum and rapidity hadrons. background processes are normalised from data themselves. inclusive branching ratio measured to be(3.11±0.80stat±0.72syst)×10−4,consistent Standard Model expectation via penguin processes.
We report a measurement of the exclusive e+ e- -->Lambda+_(c)Lambda-_(c) cross section as function center-of-mass energy near Lambda+_(c)Lambda-_(c) threshold. A clear peak with significance 8.2sigma is observed in invariant mass distribution just above With an assumption resonance origin for peak, and width M=[4634 (+8)_(-7)(stat)(+5)_(-8)(syst)] MeV/c(2) Gamma_(tot)=[92 (+40)_(-24)(stat)(+10)_(-21)(syst)] MeV are determined.

Previously published and as yet unpublished QCD results obtained with the ALEPH detector at LEP1 are presented. The unprecedented statistics allows detailed studies of both perturbative non-perturbative aspects strong interactions to be carried out using hadronic Z tau decays. presented include precise determinations coupling constant, tests its flavour independence, SU(3) gauge structure QCD, study coherence effects, measurements single-particle inclusive distributions two-particle...
We report the first observation of a charmoniumlike state recoiling from J/psi in inclusive process e+e- -->J/psi+anything at mass (3.943+/-0.006+/-0.006) GeV/c{2}. also observe decay this into D*D[over ] and determine its intrinsic width to be less than 52 MeV/c{2} 90% C.L.

The present report documents the results of Working Group 2: B, D and K decays, workshop on Flavor in Era LHC, held at CERN from November 2005 through March 2007. With advent we will be able to probe New Physics (NP) up energy scales almost one order magnitude larger than it has been possible with accelerator facilities. While direct detection new particles main avenue establish presence NP indirect searches provide precious complementary information, since most probably not measure full...
We report a study of the processes ${e}^{+}{e}^{\ensuremath{-}}\ensuremath{\rightarrow}J/\ensuremath{\psi}{D}^{(*)}{\overline{D}}^{(*)}$. In $J/\ensuremath{\psi}{D}^{*}{\overline{D}}^{*}$ we observe significant enhancement in ${D}^{*}{\overline{D}}^{*}$ invariant mass spectrum, which interpret as new charmoniumlike state and denote $X(4160)$. The $X(4160)$ parameters are $M=({4156}_{\ensuremath{-}20}^{+25}\ifmmode\pm\else\textpm\fi{}15)\text{ }\text{ }\mathrm{MeV}/{c}^{2}$...

The Collins effect connects transverse quark spin with a measurable azimuthal asymmetry in the yield of hadronic fragments around quark's momentum vector. Using two different reconstruction methods we measure statistically significant asymmetries for charged pion pairs ${e}^{+}{e}^{\ensuremath{-}}$ annihilation at center-of-mass energies 10.52 GeV and 10.58 GeV, which can be attributed to fragmentation primordial quarks components. measurement was performed using data set $547\text{ }\text{...

This enhancement may be related to one or more three states so far reported 3.90-3.95
