Search for charmonium and XYZ states in at BESIII
Within the framework of nonrelativistic quantum chromodynamics, we study the
production of charmonium states in at BESIII
with (n=1, 2, 3, and 4), (n=1, 2, and 3), and
(n=1 and 2). The radiative and relativistic corrections are
calculated to next-to-leading order for and wave states. We then argue
that the search for states such as , , ,
and in at BESIII may help clarify the nature
of these states. BESIII can search states through two body process
, where decay to , , or
. This result may be useful in identifying the nature of
states. For completeness, the production of charmonium in at B factories is also discussed.Comment: Comments and suggestions are welcome. References are update
Detection of bound entanglement in continuous variable systems
We present several entanglement conditions in order to detect bound entangled
states in continuous variable systems. Specifically, Werner and Wolf [Phys.
Rev. Lett. 86, 3658 (2001)] and Horodecki and Lewenstein [Phys. Rev. Lett. 85,
2657 (2000)] have proposed examples of bound entangled Gaussian state and bound
entangled non-Gaussian state, respectively, of which entanglement can be
detected by using our entanglement conditions.Comment: 5 pages, 1 figur
Impact of Foreign Capital on Economic Growth in Developing Countries: A Debatable Issue in India
Foreign capital is increasingly becoming a significant resource to spur economic growth in many developing countries. This present study used time series data from 1978 to 2014 to investigate the impact of foreign capital on economic growth in India. We found that external debt and foreign remittances lead positively towards economic growth on one hand while on the other hand ODA and FDI negatively affects economic growth in India. The popularly believed argument that foreign capital can help boost economic growth remains an arguable issue in India. Keywords: India, Foreign Capital, Economic Growt
