have attached the abstract to this email. For a quick view, the abstract reads as follows:</span><span style="color: rgb(0, 0, 0); background-color: rgb(255, 255, 255); display: inline !important;"></span>

<u>Photoproduction of $\Lambda*$ Resonances Using the CLAS Detector</u></div>
<div style="margin: 0px; font-size: 11pt; color: black; background-color: white;">
Much is known about the photoproduction of the hyperon resonances $\Lambda(1405)1/2^-$ and $\Lambda(1520)3/2^-$, but little is known about photoproduction to the higher-mass resonances $\Lambda(1670)1/2^-$ and $\Lambda(1690)3/2^-$. Both pairs of resonances
are spin-orbit partners and are rated as 4-star (well-known) by the Particle Data Group. In the quark model, the $\Lambda(1405)$<br>
<span style="margin:0px">and $\Lambda(1520)$ resonances are assigned to the SU(3) singlet, where the $\Lambda(1670)$ and $\Lambda(1690)$ are assigned to the octet. Using photoproduction data from the CLAS detector at Jefferson Lab, the $\Lambda(1520)$ has been
studied using two exclusive channels, $\Sigma^+ \pi^-$ and $\Sigma^- \pi^+$, from the detected $K^+$, $\pi^+$, and $\pi^-$ particles. The higher mass resonances, $\Lambda(1670)$ and $\Lambda(1690)$ <span style="margin:0px">are studied for the first time using
photoproduction.</span></span></div>
