Abstract
- We have searched for resonance production in the reaction ???K<subscript>s</subscript><superscript>0</superscript>Kp. No signal was found for the?<subscript>c</subscript> and an upper limit for the radiative with <img src="/fulltext-image.asp?format=htmlnonpaginated&src=R2641306X715321J_html\10052_2005_Article_BF01548442_TeX2GIFIE1.gif" border="0" alt=" $$\Gamma _{\gamma \gamma }^{\eta _c } $$ " /> keV (95% c.l.) is obtained. For the glueball candidate ?(1440) (previouslyi) the upper limit <img src="/fulltext-image.asp?format=htmlnonpaginated&src=R2641306X715321J_html\10052_2005_Article_BF01548442_TeX2GIFIE2.gif" border="0" alt=" $$\Gamma _{\gamma \gamma }^{\eta (1440)} B(\eta (1440) \to K\bar K\pi )< 1.2keV(95\% c.l.)$$ " /> is derived. In the tagged data sample resonance formation of a spin 1 state at 1420 MeV is observed, which is absent in the untagged data. The mass and width of this state are consistent with those of thef<subscript>1</subscript>(1420); an analysis of decay angular distributions favours positive parity.
