• The interpretation of Y(4140) as a $D^{*}_{s}\bar{D}^{*}_{s}$ molecule is studied dynamically in the one boson exchange approach, where σ, η and φ exchange are included. Ten allowed $D^{*}_{s}\bar{D}^{*}_{s}$ states with low spin parity are considered, and we find that the JPC=0++, 1+−, 0−+, 2++ and 1−−$D^{*}_{s}\bar{D}^{*}_{s}$ configurations are most tightly bound. We suggest that the most favorable quantum numbers are JPC=0++ for Y(4140) as a $D^{*}_{s}\bar{D}^{*}_{s}$ molecule; however, JPC… CONTINUE READING
