| 英文摘要 | A measurement of the shape of the differential decay rate and the associated isgur-wise function for the decay lambda(0)(b) ->+ lambda(+)(c) mu(-) is reported, using data corresponding to 3 fb(-1) collected with the lhcb detector in proton-proton collisions. the lambda(+)(c) mu(-)(nu) over bar mu (+anything) final states are reconstructed through the detection of a muon and lambda(+)(c) baryon decaying into pk(-)pi(+), and the decay lambda(0)(b) -> lambda(+)(c)pi(+)pi(-)mu(-)(nu) over bar mu are used to determine contributions from lambda(0)(b) -> lambda(c)*(+)mu(-)(nu) over bar mu decays. the measured dependence of the differential decay rate upon the squared four-momentum transfer between the heavy baryons, q(2), is compared with expectations from heavy-quark effective theory and from unquenched lattice qcd predictions. |
