Observation of the Singly Cabibbo-Suppressed Decay D + › ? ? + and Evidence for D 0 › ? ? 0
Kolcu, Onur Buğra (APS Physics, 2016)Based on 2.93 fb-1 e +e - collision data taken at center-of-mass energy of 3.773 GeV by the BESIII detector, we report searches for the singly Cabibbo-suppressed decays D + › ??+ and D 0 › ??0 . A double tag technique is ... -
Precision Measurement of the e(+)e(-) -> Lambda(+)(c)(Lambda)over-bar(c)(-) Cross Section Near Threshold
Kolcu, Onur Buğra (Amer Physical Soc., 2018)The cross section of the e(+)e(-) -> Lambda(+)(c)(Lambda) over bar (-)(c) process is measured with unprecedented precision using data collected with the BESIII detector at root s = 4574.5, 4580.0, 4590.0 and 4599.5 MeV. ... -
Search for a light CP-odd Higgs boson in radiative decays of J/psi
Kolcu, Onur Buğra (2016)We search for a light Higgs boson A0 in the fully reconstructed decay chain of J/?›?A0, A0›µ+µ- using (225.0±2.8)×106 J/? events collected by the BESIII experiment. The A0 is a hypothetical CP-odd light Higgs boson predicted ... -
Search for C-parity violation in J/? › ?? and ??
Kolcu, Onur Buğra (2014)Using 1.06×108 ?(3686) events recorded in e+e- collisions at s?=3.686??GeV with the BESIII at the BEPCII collider, we present searches for C-parity violation in J/?›?? and ?? decays via ?(3686)›J/??+?-. No significant ... -
Search for h(c) -> pi(+)pi(-) J/psi via psi(3686) -> pi(0)pi(+)pi(-) J/psi
Kolcu, Onur Buğra (Amer Physical Soc., 2018)Using a data sample of 448.1 x 10(6) psi(3686) events collected with the BESIII detector operating at the BEPCII, we perform search for the hadronic transition h(c)-> pi(+)pi(-) J/psi via psi (3686) -> pi(0)hc. No signals ... -
Search for the weak decay ?'›K±?± and precise measurement of the branching fraction B(J/?›??')
Kolcu, Onur Buğra (2016)We present the first search for the rare decay of ?' into K±?± in J/?›??', using a sample of 1.3×109 J/? events collected with the BESIII detector. No significant signal is observed, and the upper limit at the 90\% confidence ... -
Study of ? decays to the ?-?¯+ and ?(1385)±?¯(1385)± final states
Kolcu, Onur Buğra (2016)We study the decays of the charmonium resonances J/? and ?(3686) to the final states ?-?¯+, ?(1385)±?¯(1385)± based on a single baryon tag method using data samples of (223.7±1.4)×106 J/? and (106.4±0.9)×106 ?(3686) events ... -
Study of eta(1475) and X(1835) in radiative J/psi decays to gamma phi
Kolcu, Onur Buğra (Amer Physical Soc., 2018)The decay J/psi -> gamma gamma phi is studied using a sample of 1.31 x 10(9) J/psi events collected with the BESIII detector. Two structures around 1475 MeV/c(2) and 1835 MeV/c(2) are observed in the gamma phi invariant ... -
