We present the magnetic dipole(M1) transitions V→Pγ of various heavy-flavored mesons such as (D,D∗,Ds,Ds∗,ηc,J/ψ)
Nearby in the stack
and
(B,B∗,Bs,Bs∗,ηb,Υ)
using the light-front quark model constrained by the variational principle for the QCD-motivated effective Hamiltonian. The weak decay constants of heavy mesons and the decay widths for
V→Pγ
are calculated. The radiative decay for
Υ→ηbγ
process is found to be very helpful to determine the unmeasured mass of
ηb
. Our numerical results are overall in good agreement with the available experimental data as well as other theoretical model calculations.
