'''Research Description:'''
The family of B->Kmumu decays has drawn enormous attention in the last few years.
Many anomalous measurements in these decays could be hints of the existence of new particles.
A particular measurement is the ratio of decays with either up or down quarks, hence
yielding a measurement of the isospin asymmetry.
This is not expected to deviate from zero, but early measurements have shown small deviations.
New data is avalaible which can yield a twice more precise determination of the isospin asymmetry.
