Available in PDF, EPUB and Kindle. Book excerpt: A precise branching ratio measurement of the rare decay {pi}{sup 0} {yields} e{sup +}e{sup -} has been made. The measurement was made with the rare kaon decay experiment KTeV at Fermilab where the source of {pi}{sup 0}s was K{sub L} {yields} {pi}{sup 0}{pi}{sup 0}{pi}{sup 0} decaying in flight. A total of 794 fully reconstructed K{sub L} {yields} 3{pi}{sup 0} events consistent with two of the intermediate {pi}{sup 0}s decaying into {gamma}{gamma} and one into e{sup +}e{sup -} were collected. An estimated 53.2 {+-} 11.0 of these events were expected to be background. Normalizing to the {pi}{sup 0} Dalitz decay they found Br({pi}{sup 0} {yields} e{sup +}e{sup -}, (m{sub e{sup +}e{sup -}}/m{sub {pi}{sup 0}}){sup 2}> 0.95) = (6.44 {+-} 0.25(stat) {+-} 0.22(syst)) x 10{sup -8} where internal radiation, {pi}{sup 0} {yields} e{sup +}e{sup -}({gamma}), was limited by the requirement (m{sub e{sup +}e{sup -}}/m{sub {pi}{sup 0}}){sup 2}> 0.95 which separated it from the tree level Dalitz decay, {pi}{sup 0} {yields} e{sup +}e{sup -}P{gamma}.

This book was released on 2009 with total page 153 pages. Available in PDF, EPUB and Kindle. Book excerpt: Abstract: The Standard Model is the best current description of fundamental interactions and particles; however, the Standard Model has certain shortcomings which have driven particle physicists for the last 30 years to search for phenomena which provide evidence for the next theory beyond the Standard Model. To this end, using the BaBar detector, we search for evidence of the rare decay D* -> D0[pi];D0->[gamma][gamma]. The branching fraction of this decay is enhanced up to 200 times the standard model prediction in certain beyond-the-Standard-Model theories. A measurement of a significant branching fraction would provide evidence for a new theory of particle physics. We describe our search for this rare decay and an improved measurement of the associated decay, B(D0-> [pi]0 [pi]0) using an integrated luminosity corresponding to 470.5 fb−1 of e e− data collected by the BaBar detector at the PEP-II asymmetric ee− collider at SLAC from 1999-2007. We place an upper limit of B(D0->[gamma][gamma]) 2.51 X 10−6 at 90% confidence level and find B(D0-[pi]0[pi]0) = (8.4 " 0.1 " 0.4 " 0.3) X 10−4.

Available in PDF, EPUB and Kindle. Book excerpt: The authors study on the rare decay K{sub L} 2![pi]°[gamma][gamma], measure a{sub V}, and branching ratio by analyzing 96, 97 and 99 data. The measurements were taken by KTeV at Fermi National Accelerator Laboratory. After all cuts, they have 1982 K{sub L} 2![pi]°[gamma][gamma] candidate. The background level is estimated as 30%. K{sub L} 2![pi]°[gamma][gamma] branching ratio is measured as (1.29 ± 0.03(stat) ± 0.04(sys)) x 10−6. By using D'Ambrosio's theory to fit a{sub V}, a{sub V} = -( -0.31 ± 0.05(stat) ± 0.07(sys)).

Book excerpt: The BABAR experiment operating at the PEP-II ee− collider is designed to study CP violation effects in the B-meson system. From May 1999 to June 2002 approximately 81 fb−1 of data have been collected at the [Upsilon](4S) resonance, containing (87.9 ± 1.4) Million BB pairs. From this data sample the branching fraction for the decay B° 2![pi]°[pi]° has been extracted using a multi-dimensional maximum likelihood technique. With an efficiency of 20.4%, we find 3614−1{sup +15+1} B° 2![pi]°[pi]° events and measure the branching fraction to be [Beta](B° 2![pi]°[pi]°) = (2.0{sub -0.8-0.2}{sup +0.9+0.3}) x 10−6 where the first error is statistical and the second systematic. The statistical significance is 3.1[sigma] and we report an upper limit of [Beta](B° 2![pi]°[pi]°)

Book excerpt: The KTeV E799 experiment has conducted a search for the rare decay K{sub L} 2![pi]°°[gamma] via the topology K{sub L} 2![pi]°[pi]°{sub D}[gamma] (where [pi]°{sub D} 2![gamma]ee−). Due to Bose statistics of the [pi]° pair and the real nature of the photon, the K{sub L} 2![pi]°[pi]°[gamma] decay is restricted to proceed at lowest order by the CP conserving direct emission (DE) of an E2 electric quadrupole photon. The rate of this decay is interesting theoretically since chiral perturbation theory predicts that this process vanishes at level O(p4). Therefore, this mode probes chiral perturbation theory at O(p6). In this paper we report a determination of an upper limit of 2.43 x 10−7 (90% CL) for K{sub L} 2![pi]°[pi]°[gamma]. This is approximately a factor of 20 lower than previous results.

Available in PDF, EPUB and Kindle. Book excerpt: This thesis describes a search for the rare decay K{sub L} {yields} {pi}{sup 0}{pi}{sup 0}{gamma} using data from the KTeV experiment, using the topology K{sub L} {yields} {pi}{sup 0}{pi}{sub D}{sup 0}{gamma} (where {pi}{sub D}{sup 0} {yields} {gamma}e{sup +}e{sup -}). Due to Bose statistics and the real nature of the photon, the K{sub L} {yields} {pi}{sup 0}{pi}{sup 0}{gamma} decay can proceed at lowest order only by the Cp conserving direct emission of an E2 photon. The decay vanishes to O(p{sup 4}) in chiral perturbation theory and is a probe of the theory to the sixth order. The primary background to this decay consists of K{sub L} {yields} {pi}{sup 0}{pi}{sup 0}{pi}{sub D}{sup 0} events with one lost photon. The upper limit for the decay K{sub L} {yields} {pi}{sup 0}{pi}{sup 0}{gamma} presented in this thesis is 2.32 x 10{sup -7} at the 90% confidence level. This upper limit was derived from both 1997 and 1999 data, using a blind analysis. The upper limit was derived from a Feldman-Cousins method, based on a weighted total of 0.53 data events in the signal region with an expected K{sub L} {yields} {pi}{sup 0}{pi}{sup 0}{pi}{sub D}{sup 0} background of 0.37 {+-} 0.28 events. The previous upper limit for this decay was 5.6 x 10{sup -6} at the 90% confidence level.

This book was released on 2008 with total page 15 pages. Available in PDF, EPUB and Kindle. Book excerpt: The authors report the measurement of the branching fractions of the rare decays B° → D{sub s}{sup (*)+}?−, B° → D{sub s}{sup (*)+}?−, and B° → D{sub s}{sup (*)-} K{sup (*)+} in a sample of 381 x 106?(4S) decays into B{bar B} pairs collected with the BABAR detector at the PEP-II asymmetric-energy ee− storage ring. They present evidence for the decay B° → D{sub s}− K*+ and the vector-vector decays B° → D{sub s}{sup *+}?− and B° → D{sub s}{sup *-} K{sup *+}, as well as the first measurement of the vector meson polarization in these decays. They also determine the ratios of the CM-suppressed to CKM-favored amplitudes r(D{sup (*)}?) and r(D{sup (*)}?) in decays B° → D{sup (*)}{sup {+-}}?{sup {-+}} and B° → D{sup (*)}{sup {+-}}?{sup {-+}}, and comment on the prospects for measuring the Cp observable sin(2? +?).
