> Aki demonstrated his PID analysis for pi+ and pi- identification and
> showed us yields for p(e,e'pi-)pi+p, d(e,e'pi-)pp, d(e,e'pi+)nn.
> The two pion production yields are quite low, note that (e,e'pi-)
> from the proton target necessarily involves two positive charges in
> the undetected state, of which one must be an additional undetected
> pi+.
> The pi+- production yields from deuterium with two nucleons in the
> final state (nn,pp) are sizable. In case of pi+, a "dineutron" plus a
> continuum is seen in the missing mass spectrum; in case of the pi- the
> missing mass is cut off at 2.07 GeV [Aki: can you plot missing mass of
> d(e,e'pi-) just like incase of d(e,e'pi+) without cutting?]
> [It would be very interesting to also investigate the d(e,e'd)pi0 yield.]
