F-b-k get down

There are six types of quarks, known as flavors : up , down , strange , charm , top , and bottom . [4] Up and down quarks have the lowest masses of all quarks. The heavier quarks rapidly change into up and down quarks through a process of particle decay : the transformation from a higher mass state to a lower mass state. Because of this, up and down quarks are generally stable and the most common in the universe , whereas strange, charm, bottom, and top quarks can only be produced in high energy collisions (such as those involving cosmic rays and in particle accelerators ). For every quark flavor there is a corresponding type of antiparticle , known as an antiquark , that differs from the quark only in that some of its properties have equal magnitude but opposite sign .
