Dear Colleagues,
<br>
<br>
The Hall-B/EBAC Meeting is scheduled for February 22, Tuesday,
<br>
3.30 pm, room# L102/104 in the CEBAF Center.
<br>
<br>
We have the talk by Craig Roberts (ANL):
<br>
<br>
<b>"Masses of ground and excited-state hadrons"</b><br>
<br>
Abstract: I will describe the first Dyson-Schwinger equation
<br>
calculation of the light hadron spectrum that simultaneously
<br>
correlates the masses of meson and baryon ground- and excited-states
<br>
within a single framework. At the core of the analysis is a
<br>
symmetry-preserving treatment of a vector-vector contact
<br>
interaction. In comparison with relevant quantities the
<br>
root-mean-square-relative-error/degree-of freedom is 13%. Notable
<br>
amongst the results is agreement between the computed baryon masses
<br>
and the bare masses employed in modern dynamical coupled-channels
<br>
models of pion-nucleon reactions. The analysis provides insight into
<br>
numerous aspects of baryon structure; e.g., relationships between the
<br>
nucleon and Delta masses and those of the dressed-quark and diquark
<br>
correlations they contain.
