Measurement of B(psi(3770) -> gamma chi(c1)) and search for psi(3770) -> gamma chi(c2)
No full textKolcu, Onur Buğra (Arel Author)We report a measurement of the branching fraction for ?(3770)???c1 and search for the transition ?(3770)???c2 based on 2.92 fb-1 of e+e- data accumulated at s=3.773 GeV with the BESIII detector at the BEPCII collider. We measure B(?(3770)???c1)=(2.48±0.15±0.23)×10-3, which is the most precise measurement to date. The upper limit on the branching fraction of ?(3770)???c2 at a 90% confidence level is B(?(3770)???c2)<0.64×10-3. The corresponding partial widths are ?(?(3770)???c1)=(67.5±4.1±6.7) keV and ?(?(3770)???c2)<17.4 keV. © 2015 American Physical Society
Measurement of b(psi(3770) -> gamma chi(c1)) and search for psi(3770) -> gamma chi(c2)
No full textÇetin, Serkant Ali (Dogus Author)We report a measurement of the branching fraction for psi(3770) -> gamma chi(c1) and search for the transition psi(3770) -> gamma chi(c2) based on 2.92 fb(-1) of e(+)e(-) data accumulated at root s = 3.773 GeV with the BESIII detector at the BEPCII collider. We measure B(psi(3770) -> gamma chi(c1)) = (2.48 +/- 0.15 +/- 0.23) x 10(-3), which is the most precise measurement to date. The upper limit on the branching fraction of psi(3770) -> gamma chi(c2) at a 90% confidence level is B(psi(3770) -> gamma chi(c2)) gamma chi(c1)) = (67.5 +/- 4.1 +/- 6.7)keV and Gamma(psi(3770) -> gamma chi(c2)) < 17.4 keV

No full textKolcu, Onur Buğra (Arel Author) --- Makale 70 yazarlıdır.By analyzing a data set of 2.92fb-1 of e+e- collision data taken at s=3.773GeV and 106.41×106 ?(3686) decays taken at s=3.686GeV with the BESIII detector at the BEPCII collider, we measure the branching fraction and the partial decay width for ?(3770)›??c0 to be B(?(3770)›??c0)=(6.88±0.28±0.67)×10-3 and ?[?(3770)›??c0]=(187±8±19)keV, respectively. These are the most precise measurements to date

No full textWe report a measurement of the branching fraction for ψ(3770)→γχc1 and search for the transition ψ(3770)→γχc2 based on 2.92 fb−1 of e+e− data accumulated at s√=3.773 GeV with the BESIII detector at the BEPCII collider. We measure B(ψ(3770)→γχc1)=(2.48±0.15±0.23)×10−3, which is the most precise measurement to date. The upper limit on the branching fraction of ψ(3770)→γχc2 at a 90% confidence level is B(ψ(3770)→γχc2)<0.64×10−3. The corresponding partial widths are Γ(ψ(3770)→γχc1)=(67.5±4.1±6.7) keV and Γ(ψ(3770)→γχc2)<17.4 keV
