英文摘要	Using kaon secondary interactions in the material of the Belle detector, we search for both inclusive and exclusive production of the Theta(1540)(+). We set an upper limit of 2.5% at the 90% C.L. on the ratio of the e(1540)+ to A(1520) inclusive production cross sections. We also search for the Theta(1540)(+) as an intermediate resonance in the charge exchange reaction K(+)n -> pK(S)(0). We set an upper limit of Gamma(Theta+) < 0.64 MeV at the 90% C.L. for m(Theta+) = 1.539 MeV/c(2). These results are obtained from a 397 fb(-1) data sample collected with the Belle detector near the Y(4S) resonance, at the KEKB asymmetric energy e(+)e(-) collider. (c) 2005 Elsevier B.V.
