The standard model of particle theory will be rigorously tested by upcoming precision data on flavor mixing. Although the unitarity triangles (UTs) carry information about the Kobayashi-Maskawa (KM) quark mixing matrix, it explicitly contains just three parameters which is one short to completely fix the KM matrix. We have recently shown that the unitarity boomerangs (UBs) formed using two UTs, with a common inner angle, can completely determine the KM matrix and, therefore, better represents quark mixing. Out of the total 18 possible UBs, there is only one that does not involve very small angles and is the ideal one for practical uses. Although the UBs have different areas, there is, however, an invariant quantity, for all UBs, which is equal to a quarter of the Jarlskog parameter J squared. Hunting for new physics, with a unitarity boomerang, can reveal more information, than just using a UTs.
