• (ProQuest: ... denotes formulae and/or non-USASCII text omitted; see image).The suppressed decay Lambda sub( )b super(0) arrow right p pi super(-) mu super(+) mu super(-), excluding the J/ psi and psi (2S) arrow right mu super(+) mu super(-) resonances, is observed for the first time with a significance of 5.5 standard deviations. The analysis is performed with proton-proton collision data corresponding to an integrated luminosity of 3 fb super(-1) collected with the LHCb experiment. The Lambda sub( )b super(0) arrow right p pi super(-) mu super(+) mu super(-) branching fraction is measured relative to the Lambda sub( )b super(0) arrow right J/ psi ( arrow right mu super(+) mu super(-))p pi super(-) branching fraction giving ... ... where the first uncertainty is statistical and the second is systematic. This is the first observation of a b arrow right d transition in a baryonic decay. [Figure not available: see fulltext.]
