Possible existence of deeply bound kaonic nuclear systems was proposed Akaishi and Yamazaki (2002 more than a decade ago, based on an ansatz that the Lambda* = Lambda(1405) mass is 1405 MeV/c2, where the Lambda* is a Kbar-N quasi-bound state decaying to Sigma-pi. Recently, a large number of data on photo-production of Lambda(1405) in the gamma p to K+ pi0+- Sigma0-+ reaction were provided by the CLAS collaboration Moriya et al.(2013, and double-pole structure of the Lambda* has been intensively discussed by chiral dynamics analyses Roca (2013),Mai 2015, whereas we show that a Lambda* mass of 1405 MeV/c2 is deduced from the same CLAS data.
