This book was released on 2001 with total page 5 pages. Available in PDF, EPUB and Kindle. Book excerpt: Large samples of hyperon and kaon decays were collected with the Hyper CP spectrometer during two fixed-target runs at Fermilab. Based on an analysis of 110 million K pm decays from the 1997 data sample we present a branching ratio for K pm right arrow pi pm mu+ mu-. This is the first observation of K- right arrow pi- mu+ mu- decay.

This book was released on 2004 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: The Fermilab HyperCP collaboration is making precision studies of charged hyperon and kaon decays, as well as searches for rare and forbidden hyperon and kaon decays. We report here on measurements of the branching ratios of the flavor-changing neutral-current decays: K[sup[+-]][yields][pi][sup[+-]][mu][sup+][mu][sup -], and compare our results to theoretical predictions. This is the first observation of the K[sup -][yields][pi][sup -][mu][sup+][mu][sup -] decay.

Book Synopsis Measurement of the K+ --] Pi+ Nu Nu Branching Ratio by :
Download or read book Measurement of the K+ --] Pi+ Nu Nu Branching Ratio written by and published by . This book was released on 2008 with total page 40 pages. Available in PDF, EPUB and Kindle. Book excerpt: Experiment E949 at Brookhaven National Laboratory studied the rare decay K-->pi nu{ovr {nu}} and other processes with an exposure of 1.77 x 1012 k+'s. The data were analyzed using a blind analysis technique yielding one candidate event with an estimated background of 0.30 ± 0.03 events. Combining this result with the observation of two candidate events by the predecessor experiment E787 gave the branching ratio B(K+-->pi+ nu{ovr {nu}}) = (1.47{sub -0.89}{sup +1.30}) x 10−1°, consistent with the standard model prediction of (0.74 ± 0.20) x 10−1°. This is a more detailed report of results previously published [V.V. Anisimovsky et al., Phys. Rev. Lett. 93, 031801 (2004)].

This book was released on 2007 with total page 183 pages. Available in PDF, EPUB and Kindle. Book excerpt: The authors present a measurement of B([pi]0 2!e+e-[gamma])/B([pi]0 2![gamma][gamma]) using data taken in 1999 by the E832 KTeV experiment at Fermilab. The [pi]0s were produced by KL decays in flight that are fully reconstructed. They find 63,693 KL 2!3[pi]0 2![gamma][gamma] [gamma][gamma] e+e-[gamma] decays in KTeV data (an increase of a factor of ~ 20 in event statistics over previous experiments), and normalize to KL 2!3[pi]0 2!6[gamma], to extract B([pi]0 2!e+e-[gamma], me+e-> 15 MeV/c2

Download or read book D+ --] K-K+pi+ Meson Decays: A Search for CP Violation and a Measurement of the Branching Ratio written by and published by . This book was released on 2004 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: The authors have searched for a CP asymmetry in D[sup +] --> K[sup -]K[sup +][pi][sup +], D[sup +] --> [phi][pi][sup +], and D[sup +] --> [bar K]*[sup -]K[sup +] decays and measured the branching ratio of D[sup +] --> K[sup -]K[sup +][pi][sup +] decays all with a data sample of 79.9 fb[sup -1] collected by the BABAR experiment. Preliminary measurements of the CP asymmetries are A[sub CP](K[sup +]K[sup -][pi][sup [+-]]) = (1.4 [+-] 1.0(stat.) [+-] 1.1(syst.)) x 10[sup -2], A[sub CP]([phi][pi][sup [+-]]) = (0.2 [+-] 1.5(stat.) [+-] 0.8(syst.)) x 10[sup -2], and A[sub CP](K[sup [+-]][bar K]*[sup 0]) = (0.9 [+-] 1.7(stat.) [+-] 0.8(syst.)) x 10[sup -2]. These results are in agreement with previous published results, with the authors' results in the resonant modes having significantly smaller errors. Further, they obtain a preliminary branching ratio for D[sup +] --> K[sup -]K[sup +][pi][sup +] decays relative to D[sup +] --> K[sup -][pi][sup +][pi][sup +] decays of (10.7 [+-] 0.1(stat.) [+-] 0.2(syst.)) x 10[sup -2]. This result is a significant improvement over previous measurements.

Download or read book Precise Measurement of the K - to Pi -E E- Decay written by and published by . This book was released on 2011 with total page 16 pages. Available in PDF, EPUB and Kindle. Book excerpt: A sample of 7253 K{sup ±} 2![pi]{sup ±}ee−([gamma]) decay candidates with 1.0% background contamination has been collected by the NA 48/2 experiment at the CERN SPS, which allowed a precise measurement of the decay properties. The branching ratio in the full kinematic range was measured to be BR = (3.11 {+-} 0.12) x 10−7, where the uncertainty includes also the model dependence. The shape of the form factor W(z), where z = (M{sub ee}/M{sub K})2, was parameterized according to several models, and, in particular, the slope [delta] of the linear form factor W(z) = W0(1 + [delta]z) was determined to be [delta] = 2.32 {+-} 0.18. A possible CP violating asymmetry of K+ and K− decay widths was investigated, and a conservative upper limit of 2.1 x 10−2 at 90% CL was established.

Book Synopsis First Observation of the Decay Ks [yields Pi]0[mu]+[mu]− at the NA48 Experiment at CERN. by : Maria Teresa Fonseca Martín
Download or read book First Observation of the Decay Ks [yields Pi]0[mu]+[mu]− at the NA48 Experiment at CERN. written by Maria Teresa Fonseca Martín and published by . This book was released on 2005 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: A search for the KS → pi 0mu+mu- decay was performed by the NA48/1 Collaboration at the CERN SPS accelerator. Six events were found with a background expectation of 0.22+0.18-0.11 in the data collected in 2002 from the high-intensity K S run. The measured branching ratio is: BR( KS → pi0mu+mu -) = [ 2.9+1.5-1.2 (stat) +/- 0.2(syst)] x 10-9, assuming that only vector currents contribute to the matrix element, and a unit form factor.
