Observation of hc radiative decay hc › ??' and evidence for hc › ??
(2016)
A search for radiative decays of the P-wave spin singlet charmonium resonance hc is performed based on 4.48 × 108 ? events collected with the BESIII detector operating at the BEPCII storage ring. Events of the reaction ...
Search for a light CP-odd Higgs boson in radiative decays of J/psi
(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 ...

Observation of e(+)e(-) -> omega chi(c1,2) near root s=4.42 and 4.6 GeV
(2016)
BEPC-BES. Based on data samples collected with the BESIII detector operating at the BEPCII storage ring at center-of-mass energies s?>s> 4.4 GeV, the processes e+e-›??c1,2e+e-›??c1,2 are observed for the first time. With ...
Search for the weak decay ?'›K±?± and precise measurement of the branching fraction B(J/?›??')
(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
(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 ...
Grup 1, grup 2 ve grup 3 şirketleri yönetim kurullarında görev yapan kadın üyelere yönelik bir araştırma
(İstanbul Üniversitesi İşletme Fakültesi, 2016)
Birinci Sanayi Devrimi’yle birlikte kadınların ücretli işçi olarak iş gücü piyasasına girmelerinde bir artış gözlemlendiği yadsınamaz bir gerçektir. Bu dönemin akabinde, işgücü piyasasında emek arzı ile cinsiyet ilişkisi ...
