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 ...

Measurement of the Dynamics of the Decays D-s(+ )-> eta(('))e(+)nu(e)
(Amer Physic Soc., 2019)
Using e(+)e(-) annihilation data corresponding to an integrated luminosity of 3.19 fb(-1) collected at a center-of-mass energy of 4.178 GeV with the BESIII detector, we measure the absolute branching fractions BDs+->eta ...
Measurement of e(+)e(-) -> K(K)over-barJ/psi cross sections at center-of-mass energies from 4.189 to 4.600 GeV
(Amer Physical Soc., 2018)
We investigate the process e(+)e(-) -> K (K) over barJ/psi at center-of-mass energies from 4.189 to 4.600 GeV using 4.7 fb(-1) of data collected by the BESIII detector at the BEPCII collider. The Born cross sections for ...
Precise Measurement of the e+e- ??+?-J /? Cross Section at Center-of-Mass Energies from 3.77 to 4.60 GeV
(American Physical Society, 2017)
The cross section for the process e+e-??+?-J/? is measured precisely at center-of-mass energies from 3.77 to 4.60 GeV using 9 fb-1 of data collected with the BESIII detector operating at the BEPCII storage ring. Two resonant ...
Observation of e+e- ? ?+?- hc and a Neutral Charmoniumlike Structure Zc(4020)0
(American Physical Society, 2014)
Using data collected with the BESIII detector operating at the Beijing Electron Positron Collider at center-of-mass energies of ?s = 4.23, 4.26, and 4.36 GeV, we observe e+e- ? ?+?-hc for the first time. The Born cross ...
Measurement of the form factors in the decay D+ ??e+?e and search for the decay D+ ??e+?e
(American Physical Society, 2015)
Using 2.92 fb-1 of electron-positron annihilation data collected at a center-of-mass energy of s=3.773 GeV with the BESIII detector, we present an improved measurement of the branching fraction B(D+??e+?e)=(1.63±0.11±0.08)×10-3. ...
Amplitude analysis of the ? 0 ? 0 system produced in radiative J=? decays
(American Physical Society, 2015)
An amplitude analysis of the ? 0 ? 0 system produced in radiative J=? decays is presented. In particular, a piecewise function that describes the dynamics of the ? 0 ? 0 system is determined as a function ofM? 0 ? 0 from ...
Fiziksel tespitteyken kendi gözünü çıkaran bir olgunun sunulması
(İstanbul Üniversitesi, 2014)
Self-enuclation is a rare but tragic consequence of a severe mental disorder and it is strongly associated with the symptoms of religious delusions, pathological guilt, auditory hallucinations and delusions specifically ...
Volumetric Analysis of the Brain Structures of Children with Down’s Syndrome: A 3D MRI Study
(Ondokuz Mayis Universitesi, 2021)
Down’s syndrome (DS) is one of the most common genetic causes of mental and cognitive retardation. In fact, it results in a number of characteristic neuropsychological and physical symptoms, including mental retardation. ...
