Hadron Spectroscopists,
<br>
<br>
Below is a revised abstract (with Eugene, Will, and Igor) on the
Study of Kaon Identification for Hyperon Photoproduction in JLab's
Hall B CLAS12 that I would like to submit to DNP. Comments and
suggestions are appreciated.

All the best,

The CLAS12 physics program includes the study of baryon
spectroscopy in quasi-real photoproduction of a large variety of
final states. This program includes the photoproduction of singly,
doubly and triply strange hyperons. The photoproduction of the
very strange hyperon, the $\Omega^-$, is of particular interest.
Its photoproduction cross section is unknown. Furthermore, the
dynamics of the $\Omega^-$ photoproduction is unclear, as there
are no strange quarks in the initial state while there are three
in the final state. The available theoretical predictions for the
$\Omega^-$ hyperon photo- and electroproduction cross section vary
from 1 to 300 pb. As of today, there is only an upper limit of the
cross section ($\sigma_{tot} < 17$~nb at 20~GeV) reported by
SLAC. To identify the final state for $\gamma p \to \Omega^- K^+
K^+K^0$ the minimal requirement is to detect three kaons: two
$K^+$ and one $K^0_s$. The latter is identified by its decay to
$\pi^+\pi^-$. We will discuss our study of kaon identification in
CLAS12 based on Monte Carlo simulations and real data collected by
Run Group A, which used a $\sim$11~GeV beam incident on a liquid
hydrogen target.

Collaboration, and Thomas Jefferson National Accelerator Facility.
