How can we theoretically predict half lives?
 
Physics news on Phys.org
It depends on the width of a resonance's peak...
If the width is Γ then you can associate the resonance's lifetime by:
Γ=\frac{1}{t}
So in general, to find the width you need to find the cross section as a function of energies... eg Breit Wigner cross section distribution...

In another way, you can calculate the time needed for a part of your particle to leave the potential via a tunneling - for example an alpha particle leaving a heavy nuclei in the potential of strong+coulomb interaction...

Thanks for your reply. I am new to particle physics. Can you suggest any good book for a beginner?

Thread 'Schrödinger equation and classical wave equation'

Not an expert in QM. AFAIK, Schrödinger's equation is quite different from the classical wave equation. The former is an equation for the dynamics of the state of a (quantum?) system, the latter is an equation for the dynamics of a (classical) degree of freedom. As a matter of fact, Schrödinger's equation is first order in time derivatives, while the classical wave equation is second order. But, AFAIK, Schrödinger's equation is a wave equation; only its interpretation makes it non-classical...

Thread 'Quantum Entanglement is a Kinematic Fact, not a Dynamical Effect'

Insights auto threads is broken atm, so I'm manually creating these for new Insight articles. Towards the end of the first lecture for the Qiskit Global Summer School 2025, Foundations of Quantum Mechanics, Olivia Lanes (Global Lead, Content and Education IBM) stated...

Thread 'Is Maxwell's electromagnetism an effective (field) theory?'

Is it possible, and fruitful, to use certain conceptual and technical tools from effective field theory (coarse-graining/integrating-out, power-counting, matching, RG) to think about the relationship between the fundamental (quantum) and the emergent (classical), both to account for the quasi-autonomy of the classical level and to quantify residual quantum corrections? By “emergent,” I mean the following: after integrating out fast/irrelevant quantum degrees of freedom (high-energy modes...
