Abstract
We report on our measurement of the inclusive spectrum of positive
pions from the reaction on a CH2 internal
target of the ITEP proton synchrotron at
with a missing
mass resolution of about
. The goal of our experiment was
the search for the hypothetical narrow
resonance
(
width and a mass of
) with
I(JP)=even(0-), called d'. We do not see any statistically
significant d'-signal. The upper limit for d' production
cross-section in pp-interactions is near
at
PACS
