[Clas_hadron] APS abstract

[Michael Dugger]

Hi,

An undergraduate student that I work with (on the Cc list) is planning on
submitting an abstract for the April APS and was not able to post directly
to this mailing list. Below are the details of the submission she would
like to make.

ASU undergraduate student: Rebecca Osar

Conference: APS April Meeting (poster session)

Category: E04 (Hadron physics: Hadron spectroscopy and exotics)

Poster title:

Cross Section Analysis of $e p\rightarrow K^+ \Lambda^*$

Abstract:

    In nuclear particle physics, there is a discrepancy between theory and
experiment concerning the numbers of existing nucleon resonances.
Current models of nucleon resonances predict far more states than have
been observed. To investigate this problem, $\Lambda(1520)$ baryons
are reconstructed from a $K^-$ and a proton from the CLAS12 detector.
Using the reaction $e p\rightarrow K^+ K^- p$ with electrons of energy
10 GeV, the invariant mass of the $K^+ \Lambda(1520)$ system is used
to determine yields, which are efficiency corrected and normalized to
produce cross sections. The cross sections of the $K^+ \Lambda(1520)$
system assist in uncovering the resonance spectrum. In this
presentation, the cross section for the reaction $e p\rightarrow K^+
\Lambda(1520)$ in the range $W$ = 2 to 5 GeV will be presented.

Any comments/suggestions are appreciated.

Thanks for your time!

Sincerely,
Michael
