Available in PDF, EPUB and Kindle. Book excerpt: The decay[tau][sup -][yields] 2[pi][sup -][pi][sup+]3[pi][sup 0][nu][sub[tau]] has been studied with the CLEO II detector at the Cornell Electron Storage Ring (CESR). The branching fraction is measured to be (2.85[+-] 0.56[+-] 0.51) x 10[sup -4]. The result is in good agreement with the isospin expectation but somewhat below the Conserved-Vector-Current (CVC) prediction. We have searched for resonance substructure in the decay. Within the statistical precision, the decay is saturated by the channels[tau][sup -][yields][pi][sup -]2[pi][sup 0][omega][nu][sub[tau]], 2[pi][sup -][pi][sup+][eta][nu][sub[tau]], and[pi][sup -]2[pi][sup 0][eta][nu][sub[tau]]. This is the first observation of this[omega] decay mode and the branching fraction is measured to be (1.89[sub -0.67][sup+0.74][+-] 0.40) x 10[sup -4].

Download or read book First Observation of the Decay Tau- -] K- Eta Tau-neutrino written by and published by . This book was released on 2003 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: The decay[tau][sup -][yields] K[sup -][eta][nu][sub[tau]] has been observed with the CLEO II detector. The[eta] meson is reconstructed using two decay channels, [eta][yields][gamma][gamma] and[pi][sup+][pi][sup -][pi][sup 0]. The measured branching fraction is B([tau][sup -][yields] K[sup -][eta][nu][sub[tau]])= (2.6[+-] 0.5[+-] 0.5) x 10[sup -4], somewhat higher than the theoretical estimates. An improved upper limit for the second-class-current decay[tau][sup -][yields][pi][sup -][eta][nu][sub[tau]] is set, B([tau][sup -][yields][pi][sup -][eta][nu][sub[tau]])

Download or read book Search for the Decay $\tau^- \rightarrow 3\pi^- 2\pi^+2\pi^0 \nu_\tau$ written by B. Aubert and published by . This book was released on 2006 with total page 8 pages. Available in PDF, EPUB and Kindle. Book excerpt: A search for the decay of the {tau} lepton to five charged and two neutral pions is performed using data collected by the BABAR detector at the PEP-II asymmetric-energy e{sup +}e{sup -} collider. The analysis uses 232 fb{sup -1} of data at center-of-mass energies on or near the {Upsilon}(4S) resonance. We observe 10 events with an expected background of 6.5{sub -1.4}{sup +2.0} events. In the absence of a signal, we set the limit on the branching ratio {Beta}({tau}{sup -} {yields} 3{pi}{sup -}2{pi}{sup +}2{pi}{sup 0}{nu}{sub {tau}})

Download or read book First Observation of the Decay. Pi. . --]. Ee−e+. Nu. and a Determination of the Form Factors F written by and published by . This book was released on 1986 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: The radiative pion decay .pi. .-->. ee−e+.nu. has been observed for the first time with a branching ratio of (3.4 +- 0.5) x 10−9. From the kinematical distribution of 79 events information on the form factors was extracted. The vector form factor F/sub V/ was found to have the same sign as the pion decay constant f/sub .pi./. For the axial-vector form factors the following values have been measured: .gamma. = F/sub A//F/sub V/ = 0.7 +- 0.5 and xi = R/F/sub V/ = 2.3 +- 0.6. This value of .gamma. agrees well with the small positive value of (0.53 +- 0.06) and excludes the large negative value obtained in .pi.+ .-->. e+.nu gamma. experiments. 8 refs. 8 refs.

Book Synopsis Observation of the Decay D{sub S} 2![omega][pi]. by :
Download or read book Observation of the Decay D{sub S} 2![omega][pi]. written by and published by . This book was released on 2003 with total page 10 pages. Available in PDF, EPUB and Kindle. Book excerpt: Using ee− annihilation data collected by the CLEO II detector at CESR, we have observed the decay D{sub s} 2![omega][pi]+. This final state may be produced through the annihilation decay of the {sub s}+, or through final state interactions. We find a branching ratio of [Lambda](D{sub s}+ 2![omega][pi]+)/[Lambda](D{sub s}+ 2![eta][pi]+) = 0.016 ± 0.04 ± 0.03, where the first error is statistical and the second is systematic.
