Measurement of the matrix elements for the decays eta -> pi(+)pi(-)pi(0) and eta/eta ' -> pi(0)pi(0)pi(0)
(American Physical Society, 2015)
Based on a sample of 1.31×109 J/? events collected with the BESIII detector at the BEPCII collider, Dalitz plot analyses of selected 79,625 ???+?-?0 events, 33,908 ???0?0?0 events, and 1,888 ????0?0?0 events are performed. ...
Observation and spin-parity determination of the X(1835) in J/? ? ?K0SK0S?
(American Physical Society, 2015)
We report an observation of the process J/? ? ?X(1835) ? ?K0SK0S? at low K0SK0S mass with a statistical significance larger than 12.9? using a data sample of 1.31 × 109 J/? events collected with the BESIII detector. In ...
Improved measurement of the absolute branching fraction of D+ -> (K)over-bar(0)mu(+)nu(mu)
(Springer, 2016)
By analyzing 2.93 fb(-1) of data collected at root s = 3.773 GeV with the BESIII detector, we measure the absolute branching fraction B(D+ -> (K) over bar (0) (+)(mu)nu(mu)) = (8.72 +/- 0.07(stat). +/- 0.18(sys).) %, which ...
Linear Modeling of Multiple Sclerosis and Its Subgroubs
(Turkish Neurological Soc., 2015)
Objective: In this study, 120 patients diagnosed with clinical multiple sclerosis (MS) of relapsing remitting type (RRMS), secondary progressive type (SPMS) and primary progressive type (PPMS) were examined, as well as 19 ...
Study of J/psi -> eta phi pi(+)pi(-) at BESIII
(American Physical Society, 2015)
Based on a sample of 2.25×108J/? events taken with the BESIII detector at the BEPCII collider, we present the results of a study of the decay J/?????+?-. The Y(2175) resonance is observed in the invariant mass spectrum of ...
Stochastic Enhancement of High-order Harmonic Generation
(IOP PUBLISHING LTD, 2012)
Here we demonstrate that from the combination of fundamental laser and noise it is possible to enhance harmonic intensities by 5 orders of magnitude with a modest noise-to-laser amplitude ratio.
Plow, Adolescent Fertility and Foreign Direct Investment
(ADAPT UNIV PRESS, 2019)
Purpose - The purpose of this paper is to examine the impact of adolescent fertility on Foreign Direct Investment (FDI). We used cross country data for the year of 2014 to unravel the causal relation. Design/methodology/approach ...
Search for baryon and lepton number violation in J/psi -> Lambda(+)(c)e(-) + c.c.
(Amer Physic Soc., 2019-04-12)
Using 1.31 x 10(9) J/psi events collected by the BESIII detector at the Beijing Electron Positron Collider, we search for the process J/psi -> Lambda(+)(c)e(-) + c.c. for the first time. In this process, both baryon and ...

Measurement of the proton form factor by studying e+e- ?p p ¯
(American Physical Society, 2015)
Using data samples collected with the BESIII detector at the BEPCII collider, we measure the Born cross section of e+e-?pp¯ at 12 center-of-mass energies from 2232.4 to 3671.0 MeV. The corresponding effective electromagnetic ...
