BESⅢ Observes New leptonic Decay Mode for D Meson
收藏 引用
Bulletin of the Chinese Academy of Sciences 2019年 第4期33卷 241-241页
作者: GUO Lijun Interncitioncil Office Institute of High Energy PhysicsCAS
The Beijing Spectrometer(BESIII)collaboration has reported the world’s first observation of the decay D+→τ+ν,which is the second type of pure leptonic decay of the D+meson,in a newly published Physical Review Lett... 详细信息

Properties of Charmonium States in a Phenomenological Approach
收藏 引用
Communications in Theoretical Physics 2019年 第2期71卷 192-202页
作者: Praveen P D’Souza Antony Prakash Monteiro K.B.Vijaya Kumar Department of Physics St Philomena College Department of Physics Mangalore University
We investigate the spectrum and decay rates of charmonium states within the framework of the non relativistic quark model by employing a Coulomb like potential from the perturbative one gluon exchange and the linear c... 详细信息

Charmonium Spectrum and Their Transitions in Relativistic Quark Models
收藏 引用
Communications in Theoretical Physics 2011年 第6期55卷 1044-1048页
作者: Bhaghyesh K.B. Vijaya Kumar Department of Physics Mangalore UniversityMangalagangotriMangalore 574 199India
Using the phenomenological relativistic harmonic model (RHM) for quarks, we have obtained the masses of S wave charmonium states. The full Hamiltonian used in the investigation has Lorentz scalar plus vector confine... 详细信息
