[Frost] Abstract for NSTAR and INPC Hadron Structure conferences

[Eugene Pasyuk]

Ross,

The title needs some improvement. "Using" in this context is not the right word, it should be "in" or "for".
Something like: "Determination of T and F observables in $\eta$ photoproduction with 
the CLAS and the Frozen Spin Target (FROST)." 
Other than that it looks fine.

> Polarization observables are an important tool for understanding and
> clarifying baryon resonance spectra. Recently, experiments were
> conducted at Jefferson Lab using a polarized photon beam incident on
> a
> polarized frozen spin target (FROST). We present preliminary data of
> the T and F asymmetries for $\eta$ photoproduction from the proton,
> along with comparisons to theoretical predictions. The data used in
> the present analysis were taken during the second running period of
> FROST using the CLAS detector at Jefferson Lab, which utilized
> transversely polarized protons in a butanol target and an incident
> tagged photon energy between 0.62 and 2.93 GeV. The T asymmetry is
> the
> observable related to transverse target polarization and the world
> database currently contains 38 such measurements. The F asymmetry is
> a
> double-polarization observable that requires circular beam
> polarization in addition to transverse target polarization. There
> have
> been no published measurements of F .
