This study investigates a recently-observed NΔ (d*) resonance decaying to the πd final state using CLAS at Jefferson Lab, Virginia. Tagged photons with beam energies between 0.8 and 3.6 GeV were produced using the Bremsstrahlung process incident on a liquid deuterium target. The final state particles detected were an energetic deuteron and two oppositely charged pions. The peak of the resonance-like structure is at about 2150 MeV. The possible d* resonance has been seen in two CLAS datasets1. Partial-wave analysis of pion-deuteron scattering has also shown a resonance at a mass of about 2145 MeV in the 1D2 partial wave. A preliminary differential cross section measurement of this possible resonance will be presented.
