[G12] DNP abstract

[Diane Schott]

Hi guys,

I'm thinking of submitting an abstract to the fall DNP meeting. Here is my
abstract, please let me know what you think.

Title:
The Search for a $\pi_1(1400)$ Exotic Meson in the $\gamma
p\to\Delta^{++}\eta\pi^-$ System with CLAS

Abstract:
The reaction $\gamma p\to\Delta^{++}X\to p\pi^+\pi^-(\eta)$ is being
studied, with the CLAS detector in Hall B at Jefferson Lab. The resonance
spectrum, $X$, shows contributions from $a_0(980)$ and $a_2(1320)$ in the
intermediate states. A PWA of the resonance spectrum has been started and
will conclude if there is a $\pi_1(1400)$ present under the $a_2(1320)$
distribution. The presence of the $\Delta^{++}$ restricts the isospin of
the possible $X$ states, leaving the PWA with a smaller combination of
partial waves, making it ideal to look for the $\pi_1(1400)$. The
$\pi_1(1400)$ has been produced with the use of hadron-production
previously but has yet to be conclusive with photo-production. The
experimental moments have been calculated and the PWA has been started. We
will discuss the data trends, along with the PWA technique being
implimented.
