Abstract: In this work the Lippmann–Schwinger equation is used to model seismic waves in strongly scattering acoustic media. We consider the Helmholtz equation, which is the scalar wave equation in the frequency domain with constant density… read more here.

Abstract: We predict the masses of the low-lying Bc mesons with JP=0-,1-,0+,1+,2+, using a flavor-dependent interaction pattern which gives an unified successful description of the light, heavy-light, and heavy mesons and is also applicable to the… read more here.
