We formulated the Lambda(1405) (abbreviated as Lambda^*) --> (Sigma pi)^0invariant-mass spectra produced in p+p --> p + Lambda^* + K^+ reactions, inwhich both the incident channel for a quasi-bound K^-p state and its decayprocess to (Sigma pi)^0 were taken into account realistically. We calculatedM(Sigma pi) spectral shapes for various theoretical models for Lambda^*. Theyare asymmetric and skewed, and were compared with recent experimental data ofHADES, yielding M(Lambda^*) = 1405 -9 +11 MeV/c^2 and Gamma = 62 +- 10 MeV,where the interference effects of the Kbar N-Sigma pi resonance with I= 0 and 1Sigma pi continuum are considered. The nearly isotropic proton distributionobserved in DISTO and HADES is ascribed to a short collision length in theproduction of Lambda^*, which justifies the high sticking mechanism of Lambda^*and the participating proton into K^-pp.
