Abstract
"Light mesons from decays of tau lepton and D mesons"
A. C. dos Reis
Centro Brasileiro de Pesquisas Físicas, Rio de Janeiro
Hadronic decays of lepton and D mesons have become a very
interesting source of information about light mesons.
In D decays the initial state is always
JP=0-
and the non-resonant component is generally small, providing a
very clean environment for measuring resonance parameters.
The decay
->
+
-
+
is a powerful tool
for studying the a1
state. We will present recent results on the
D+,Ds+ ->
+
-
+
decay from Fermilab E791 experiment,
and discuss the prospects of this promising field.
