## Analysis of distribution amplitudes and decay constants of B meson in the light-front quark model

### Description

We study the quark distribution amplitudes $\phi_{M} (x)$ and decay constants of pseudoscalar and vector $B$ meson within the light-front framework. We apply the variational method to the QCD-motivated Hamiltonian with the Gaussian-type trial wave function to obtain the scale parameter $\beta$. After fixing the parameters, we obtain the numerical results for the corresponding decay constants. The results for quark distribution amplitudes of heavy B meson are plotted.
