Dear all,<br>
this is a reminder for today's seminar.<br>
Because of the GlueX meeting, we have to move to room F113<br>

<b>Electromagnetic interactions with light baryons in covariant
ChPT</b><br>
<font color="#0f61c8"><br>
</font>We study the low-energy behaviour of baryons subjected to
external electromagnetic fields, using fully covariant ChPT with
the explicit inclusion of spin-3/2 degrees of freedom. The
processes studied are Compton scattering off baryon targets, as
well as meson photoproduction.<br>
On the one hand, the goal of the study of scattering reactions
is to extract clean information about observables such as
polarizabilities, electric dipole moments, charge radii and
electromagnetic densities. On the other hand, the analysis of
meson-production cross sections allows one to get information
about LECs, resonances and the convergence behaviour of ChPT.<br>
We predicted some hyperon electromagnetic properties for the
first time, and also achieved the reproduction of the threshold
neutral pion photoproduction data up to photon energies above
200 MeV.<br>
