Abstract

Using a large sample of charm semileptonic decays collected by the FOCUS photoproduction experiment at Fermilab, we present evidence for a small, even spin K ^-π ⁺ amplitude that interferes with the dominant K* ⁰ component in the D ⁺ → K ^-π ⁺μ ⁺ν final state. Although this interference significantly distorts the D ⁺ → K ^-π ⁺μ ⁺ν decay angular distributions, the new amplitude creates only a very small distortion to the observed kaon pion mass distribution when integrated over the other kinematic variables describing the decay. Our data can be described by K* ⁰ interference with either a constant amplitude or broad spin zero resonance.

N2 - Using a large sample of charm semileptonic decays collected by the FOCUS photoproduction experiment at Fermilab, we present evidence for a small, even spin K -π + amplitude that interferes with the dominant K* 0 component in the D + → K -π +μ +ν final state. Although this interference significantly distorts the D + → K -π +μ +ν decay angular distributions, the new amplitude creates only a very small distortion to the observed kaon pion mass distribution when integrated over the other kinematic variables describing the decay. Our data can be described by K* 0 interference with either a constant amplitude or broad spin zero resonance.
