Peluruhan proton

Pada fisika partikel, peluruhan proton adalah sebuah wujud peluruhan partikel hipotetis, yang mana proton meluruh menjadi partikel subatom yang lebih ringan seperti pion netral dan sebuah positron.[1] Hipotesis peluruhan proton pertamakali dirumuskan oleh Andrey Sakharov pada 1967. Meski upaya signifikan untuk menguji coba hal ini, hingga saat ini peluruhan proton tidak pernah diamati. Jika proton benar-benar dapat meluruh melalui sebuah positron, waktu paruhnya adalah sekitar 1,67×1034 yr.[2]
