It has been long thought that proton is made out of two up and one down quark. However, after the realization that these quark spins was making up only a certain amount of the proton's spin, an update on our imagination of proton became inevitable. This work is an attempt to evolve our imagination. The hint perhaps lies on another quark flavor known as strange quark. A trace leading to presence of strange quark(s) inside proton would be the conclusive evidence. Parity violation is an indispensable tool for searching for this type of trace(s).
