We have observed a very sharp peak in the cross section for ${e}^{+}{e}^{\ensuremath{-}}\ensuremath{\rightarrow}\mathrm{hadrons}, {e}^{+}{e}^{\ensuremath{-}}$, and possibly ${\ensuremath{\mu}}^{+}{\ensuremath{\mu}}^{\ensuremath{-}}$ at center-of-mass energy of 3.105\ifmmode\pm\else\textpm\fi{}0.003 GeV. The upper limit to full width half-maximum is 1.3 MeV.
We have found events of the form e++e−→e±+μ∓+missingenergy, in which no other charged particles or photons are detected. Most these detected at above a center-of-mass energy 4 GeV. The missing-energy and missing-momentum spectra require that least two additional be produced each event. conventional explanation for events.Received 18 August 1975DOI:https://doi.org/10.1103/PhysRevLett.35.1489©1975 American Physical Society
We present evidence, from a study of multihadronic final states produced in ${e}^{+}{e}^{\ensuremath{-}}$ annihilation at center-of-mass energies between 3.90 and 4.60 GeV, for the production new neutral state with mass 1865\ifmmode\pm\else\textpm\fi{}15 MeV/${\mathit{c}}^{2}$ decay width less than 40 that decays to ${K}^{\ifmmode\pm\else\textpm\fi{}}{\ensuremath{\pi}}^{\ensuremath{\mp}}$...
We have observed a second sharp peak in the cross section for ${e}^{+}{e}^{\ensuremath{-}}\ensuremath{\rightarrow}\mathrm{hadrons}$ at center-of-mass energy of 3.695\ifmmode\pm\else\textpm\fi{}0.004 GeV. The upper limit full width half-maximum is 2.7 MeV.
We have found evidence for jet structure in ${e}^{+}{e}^{\ensuremath{-}}\ensuremath{\rightarrow}\mathrm{hadrons}$ at center-of-mass energies of 6.2 and 7.4 GeV. At GeV the jet-axis angular distribution integrated over azimuthal angle was determined to be proportional $1+(0.78\ifmmode\pm\else\textpm\fi{}0.12){cos}^{2}\ensuremath{\theta}$.
We report evidence for the production of a new narrow charged state in e+e− annihilation at center-of-mass energy 4.03 GeV. This state, which has mass 1876± 15 MeV/c2, is observed exotic channel K∓π±π±, but not nonexotic K∓π+π−. It produced primarily association with system 2.01±0.02 GeV/c2. These characteristics are just those expected charmed meson.Received 21 July 1976DOI:https://doi.org/10.1103/PhysRevLett.37.569©1976 American Physical Society
In grapevine, as in other fruit crops, size and seed content are key components of yield quality; however, very few Quantitative Trait Loci (QTLs) for berry weight (number, weight, dry matter percentage) have been discovered so far. To identify new stable QTLs marker-assisted selection candidate gene identification, we performed simultaneous QTL detection four mapping populations (seeded or seedless) with various genetic backgrounds. For identified five QTLs, on linkage groups (LGs) 1, 8,...
The T2K (Tokai-to-Kamioka) experiment is a long baseline neutrino oscillation in Japan, for which near detector complex (ND280), used to characterize the beam, will be built 280 m from target off-axis direction of beam produced using 50 GeV proton synchrotron J-PARC (Japan Proton Accelerator Research Complex). central part ND280 including 3 large Time Projection Chambers based on Micromegas gas amplification technology with anodes pixelated into about 125,000 pads and requiring therefore...
We observe a resonancelike structure in the total cross section for hadron production by ${e}^{+}{e}^{\ensuremath{-}}$ colliding beams at mass of 4414 \ifmmode\pm\else\textpm\fi{} 7 MeV having width $\ensuremath{\Gamma}=33\ifmmode\pm\else\textpm\fi{}10$ MeV. From area under this resonance, we deduce partial to electron pairs be ${\ensuremath{\Gamma}}_{\mathrm{ee}}=440\ifmmode\pm\else\textpm\fi{}140$ eV. Further comparable is present near 4.1 GeV.
Measurements of multihadron production in e+e− annihilation at center-of-mass energies between 2.6 and 7.8 GeV are presented. Aside from the narrow resonances ψ(3095) ψ(3684), total hadronic cross section is found to be approximately 2.7 times for muon pairs c.m. below 3.7 4.3 muon-pair above 5.5 GeV. Complicated structure intermediate energies. Charged-particle multiplicities inclusive momentum distributions presented.Received 12 April 1982DOI:https://doi.org/10.1103/PhysRevD.26.969©1982...
We present measurements of inclusive anomalous muon production in e+e− annihilations three energy ranges. In all ranges we observe a large rate two-prong events which is compatible with the expected decays pairs heavy leptons. highest range there also appreciable multiprong which, due to its magnitude and momentum dependence, must come part from source other than lepton.Received 8 November 1976DOI:https://doi.org/10.1103/PhysRevLett.38.117©1977 American Physical Society
We present experimental evidence for the existence of decay ψ(3684)→γχ, χ→4π±, 6π±, π+π−K+K−, π+π−, and K+K−. There is clear at least two χ states, one 3.41 ± 0.01 GeV/c2 other 3.53±0.02 GeV/c2. The χ(3410) decays into ππ KK thus must have even spin parity.Received 11 August 1975DOI:https://doi.org/10.1103/PhysRevLett.35.821©1975 American Physical Society
We observe $\ensuremath{\psi}(3684)$ to decay into $\ensuremath{\psi}(3095)$ with a branching ratio of 0.57 \ifmmode\pm\else\textpm\fi{} 0.08. The for the particular mode $\ensuremath{\psi}(3095)+{\ensuremath{\pi}}^{+}+{\ensuremath{\pi}}^{\ensuremath{-}}$ is measured be 0.32 0.04. Remaining decays leading are largely, but not entirely, accounted by $\ensuremath{\psi}(3095)+{\ensuremath{\pi}}^{0}+{\ensuremath{\pi}}^{0}$ if two pions in this state zero isospin.
Phenomic prediction has been defined as an alternative to genomic by using spectra instead of molecular markers. A reflectance spectrum provides information on the biochemical composition within a tissue, itself being under genetic determinism. Thus, relationship matrix built from could potentially capture signal. This new methodology mainly applied in several annual crop species but little is known so far about its interest perennial species. Besides, phenomic only tested for restricted set...
