Example Kaon Mass Calculation

(Remember: m_π= 0.140 GeV/c², so/font> m_πc² = 0.140 GeV)
If your radius measurements give p₁ = 0.367 GeV/c, put p₁c = 0.367 GeV, then:

(1)

If your radius measurements give p₂ = 0.594 GeV/c, put p₂c = 0.594 GeV, then:

(2)

For this example θ = 51.653 . We can now calculate m_K


	(3)

This is very close to the accepted value of

Neutral kaon rest mass, m_K = 0.497 GeV/c²
