[Clas_hadron] Abstract: APS April Meeting 2016

[Hicks, Kenneth]

Hi Volker,

Sorry about the confusion about the last sentence of Taya's abstract.  We'll revise the wording, but the main result is that we see the d* resonance in the invariant mass of the d-pi0 system.  This fills in the missing isospin state (the CMU group say resonances in d-pi+ and d-pi-).  So technically, the overlap is with d* rho+ and d* rho- where the charged rho meson decays to two pions.  As you point out, this was not clear from the abstract. 

Ken

Hi Taya,

A couple of comments:

1) It is unclear from the text where the experiment was carried out.
  Please refer to the Jefferson Lab and its CW accelerator.

2) The last sentence is misleading. Interference can only occur for the
same final state not between a final state (d-omega) and a resonances
(d*). Only if d* couples to d-omega can you expect interference. Is it
known that d* couples to the d-omega final state?  If you see
interference-like effects in the d-omega cross section data near the
mass of d*, it means that d* is coupling to d-omega final state, and it
would give further evidence that d* is a real resonance. You should also
give the mass of the d* dibaryon observed in pi-d scattering.

Good luck with the abstract.
Volker
