B~0(B+s)→γvv decays are useful to determining the decay constants f_B(f_B_s) and B(B_s) meson wavefunction.Using the B meson wave function determined in hadr
The contributions of the currents and the Coulomb interaction to multipole excitations are studied in the framework of a fully consistent relativistic continuum
Gauge symmetry imposes powerful constraints on the basic vertex functions of gauge theories,leading to the exact relations among Green’s functions,referred to
CYCIAE-100,the high intensity compact cyclotron under construction in CIAE,is designed to extract proton beam from 75 MeV to 100 MeV in two opposite directions
The general way to generate isochronous field in a separated sector cyclotron is the kb-kr method.It is based on abundant data of magnetic field measurement,tha
