WebAug 1, 2015 · The total decay width is obtained by integration over the scattering spectrum of the free Hamiltonian, (2.7) Γ ¯ = ∫ 0 ∞ d E d Γ ¯ ( E) d E. This formula is valid when the energy E is the only quantum number needed to describe the stable, asymptotic states. WebFeb 7, 2024 · In this video, we will talk about the decay width and lifetime of unstable particles. Apart from elementary particles, like the electron or quarks, the only ...

WebNov 1, 2024 · After a continuum extrapolation, the decay width is obtained to be $\Gamma_{\gamma\gamma}(\chi_{c0})=3.40(1.10)_{\mathrm{stat}}\, \textrm{keV}$. Albeit this large statistical error, our result is ... WebThe width of such a distribution of mass energies is called the decay width Γ and is measured in units of energy. The decay width is related to the uncertianty in energy as follows. Γ = 2ΔE = ℏ τ = ℏλ where λ is the decay constant.
