Percentage and Ratio are two of the most fundamental concepts in Quantitative Aptitude and form the backbone of topics asked in bank exams, insurance, and other competitive tests. A strong command ...

We report a measurement of the ratios of the decay rates of the B~+, B~0 and B~0_s mesons into exclusive final states containing a J/psi meson. The final states were selected from 19.6 pb~{-1} of ...

Fractions are the basis for most higher-level mathematics. Students need to master the numerical values in earlier grades to tackle topics like algebra later. There’s only one hitch: Fractions can ...

The ratio of charged and neutral B meson production at the Upsilon(4S), f_{+-}/f_{00}, is measured through the decays B bar -> D* l- nu_l bar, reconstructed using a partial reconstruction method where ...

Fractions are an essential concept in mathematics used to represent parts of a whole. They express a number that is not whole, breaking down values into smaller, equal parts. Here’s a breakdown of ...
