The neutrino oscillations imply that at least two neutrinos have non-zero masses[1].However,up to now,we only measure the differences of neutrino mass squares in a standard scenario with three massive eigenstates[2],i.e.

The( p, q) inflation model
《Science China(Physics,Mechanics & Astronomy)》2015年第11期63-67,共5页HUANG QingGuo 
supported by the project of Knowledge Innovation Program of Chinese Academy of Sciences,and the National Natural Science Foundation of China(Grant Nos.10821504,11322545 and 11335012)
In this paper we propose a new inflation model named( p, q) inflation model in which the inflaton potential contains both positive and negative powers of inflaton field in the polynomial form. We derive the accurate p...

An accurate determination of the Hubble constant from baryon acoustic oscillation datasets被引量：1
《Science China(Physics,Mechanics & Astronomy)》2015年第9期103-108,共6页CHENG Cheng HUANG QingGuo 
supported by the Project of Knowledge Innovation Program of Chinese Academy of Science,National Natural Science Foundation of China(Grant Nos.11322545 and 11335012)
Even though the Hubble constant cannot be significantly determined just by the low-redshift Baryon Acoustic Oscillation(BAO)data, it can be tightly constrained once the high-redshift BAO data are combined. We combined...
