Complete Measurement of the. Electromagnetic Form Factors
BESIII Collaboration; Kolcu, Onur Bugra (AMER PHYSICAL SOC, 2019)The exclusive process e(+)e(-) -> Lambda(Lambda) over bar, with Lambda -> p pi(-) and (Lambda) over bar -> (p) over bar pi(+), has been studied at root s = 2.396 GeV for measurement of the timelike Lambda electric and ... -
Improved measurements of the absolute branching fractions of the inclusive decays D+(0) -> phi X
BESIII Collaboration; Kolcu, Onur Bugra (AMER PHYSICAL SOC, 2019)By analyzing 2.93 fb(-1) of e(+)e(-) annihilation data taken at the center-of-mass energy root s = 3.773 GeV with the BESIII detector, we determine the branching fractions of the inclusive decays D+-> phi X and D-0 -> phi ... -
Measurements of weak decay asymmetries of Lambda(+)(c) -> pK(S)(0), Lambda pi(+), Sigma(+)pi(0), and Sigma(0)pi(+)
BESIII Collaboration; Kolcu, Onur Bugra (AMER PHYSICAL SOC, 2019)Using e(+)e(-) -> Lambda(+)(c)(Lambda) over bar (-)(c). production from a 567 pb(-1) data sample collected by BESIII at 4.6 GeV, a full angular analysis is carried out simultaneously on the four decay modes of Lambda(+)(c) ... -
