${{\boldsymbol D}_{{3}}^{*}{(2750)}}$ POLARIZATION AMPLITUDE A$_{{{\boldsymbol D}}}$
INSPIRE search
A polarization amplitude A$_{{{\mathit D}}}$ is a parameter that depends on the initial polarization of the ${{\mathit D}_{{3}}^{*}{(2750)}}$. For ${{\mathit D}_{{3}}^{*}{(2750)}}$ decays the helicity angle, ${{\mathit \theta}_{{H}}}$, distribution varies like 1 + A$_{{{\mathit D}}}$ cos $({{\mathit \theta}_{{H}}})$, where ${{\mathit \theta}_{{H}}}$ is the angle in the ${{\mathit D}^{*}}$ rest frame between the two pions emitted by the ${{\mathit D}_{{3}}^{*}{(2750)}}$ $\rightarrow$ ${{\mathit D}^{*}}{{\mathit \pi}}$ and ${{\mathit D}^{*}}$ $\rightarrow$ ${{\mathit D}}{{\mathit \pi}}$ .
