北京谱仪Ⅲ实验a0和f0研究获进展（图）
北京 谱仪Ⅲ实验 a0 f0
2018/7/19
2018年7月11日，《物理评论快报》（Physical Review Letters）以“编辑推荐”的形式发表了北京谱仪Ⅲ (BESⅢ)实验的研究成果Observation of -f0(980) Mixing（Phys. Rev. Lett. 121, 022001 (2018)）。和f0(980)(简称a0和f0)是标量介子，其性质一直存在争议。除了被认为是夸克反夸克构成的普通介子态，在理论...
Long-term trends in f0 F2 over Grahamstown using Neural Networks
Solar activity magnetic activity
2015/9/25
Many authors have claimed to have found long-term trends in f0 F2 , or the lack thereof, for different stations. Such investigations usually involve gross assumptions about the variation of f0 F2 with...
The effects of f0 F2 variability on TEC prediction accuracy
ionopshere ionospheric modelling
2015/9/25
In this paper hourly daily F2-layer critical frequency data recorded at Rome and one minute daily TEC data recorded at Florence were used and the relevant variabiles were calculated. It was concluded ...
Variation of the feedback coefficient with R12 and the geographic latitude in 1-h ahead forecast of f0 F2
forecast feedback critical frequency
2015/9/25
The «prediction» and «forecast» of the critical frequency of the F 2 layer (f0 F2 ) is an important issue for frequency planning in short wave radio communications. In this context...

Study of a0(980)-f0(980) mixing at BES III and study of charged kappa at BES II
(980)-f0(980) charged kappa at BES II
2011/1/5
Recent BES results on light scalars are reported in this talk, including the observation of a charged k± decaying to K±p 0 with 5.8×107 J/y data at BES II and the directmeasurements of a00 (980)−...
In this proceeding, we propose to directly measure the a00(980)-f0(980) mixing in J/ψ→φ f0(980)→φa00(980) and χc1→π0φa00(980)→π0f0(980) with the upgraded Beijing Electron Positron Collider(BEPCII) wit...
No indication of f0(1370) in pi pi phase shift analyses
pion pion scattering scalar mesons glueball
2010/3/15
The scalar meson f_0(1370) - indicated in particular in the low energy p\bar p \to 3 body reactions - is a crucial element in certain schemes of the scalar meson spectroscopy including glueballs. The ...
We investigate the D0-D0 mixing through the doubly Cabibbo suppressed (DCS) channel D0→f0(980)K*0 and its charge conjugate channel, in which the K*0 meson is reconstructed in both K+π－ and KSπ0 final ...
