Study on the ϒ(1S)→BcDs decay
Nuclear Physics B, 2016 The branching ratio and direct CP asymmetry of the ϒ(1S)→BcDs weak decay are estimated with the perturbative QCD approach firstly. It is found that (1) the direct CP-violating asymmetry is close to zero, (2) the branching ratio Br(ϒ(1S)→BcDs)≳10−10 might Junfeng Sun, Yueling Yang, Qingxia Li, Haiyan Li, Na Wang, Qin Chang, Jinshu Huang +6 moredoaj +1 more sourceSecond Generation Leptoquark Search in p\bar{p} Collisions at $\sqrt{s}$

, 1995 We report on a search for second generation leptoquarks with the D\O\
detector at the Fermilab Tevatron $p\bar{p}$ collider at $\sqrt{s}$ = 1.8 TeV.
This search is based on 12.7 pb$^{-1}$ of data.A. A. Mayorov, A. A. Volkov, A. Baden, A. Bischoff, A. Boehnlein, A. Brandt, A. Bross, A. Goldschmidt, A. Jonckheere, A. K. A. Maciel, A. Kernan, A.

, 2016 The standard model predicts that, in addition to a proton, an electron, and
an antineutrino, a continuous spectrum of photons is emitted in the $\beta$
decay of the free neutron. We report on the RDK II experiment which measured

Physics Letters, 1966 Abstract Analysis of 100 000 K − p interactions in the 72-in. bubble chamber has yielded branching ratios for ϑ decay, particularly for rarer modes (ϱπ,ηγ) for which little data have been available. Partial decay rates are compared with predictions of the Sakurai-Glashow “ϑω” mixing theory and used to determine the ϑ spin.Lindsey, James S., Smith, Gerald A.openaire +2 more sourcesShape coexistence from lifetime and branching-ratio measurements in 68,70Ni

Physics Letters B, 1997 We report a measurement of the branching ratio B(D+ → ϱ0l+νl)B(D+ → K∗0l+νl) from the Fermilab charm hadroproduction experiment E791. Based on signals of 49 ± 17 events in the D+ → ϱ0e+νe mode and 54 ± 18 events in the D+ → ϱ0μ+νμ mode, we measure.
