@mfb: Thank you for your answer, this really seems to be the case. Could you suggest some literature, a standard book or an article on this issue. I just can't seem to find this anywhere. Thanks again!

So the total lifetime of a particle with miltiple decay channels is {1\over\tau_{\rm tot}}=\sum\limits_i{1\over\tau_i}\;. And the probability for such a particle to live for a time t is P_s(t)=\exp\left(-{t\over\gamma\tau_{\rm tot}}\right)= \prod_i \exp\left(-{t\over\gamma\tau_i}\right)\...

@MarekS P_s(t)=1-\sum_i p_i \int\limits_0^t{1\over\gamma\tau_i}\exp\left(-{t'\over\gamma\tau_i}dt'\right) Is this what you meant? @Myphyclassnot: for nuclear and particle physics see e.g. Griffiths, Povh, Perkins, Halzen & Martin, Peskin & Schroeder, Bjorken & Drell ... @mfb: yes, i...

Particle can decay through many channels with probabilities p_i, where in each channel its decay time is different \tau_i. It always decays through one of the channels. Particle decays according to exponential law where probability to decay in time t is...

In my case \mu_B is nuclear magneton \mu_N={e\hbar\over2m_P} as I'm dealing with a proton. Thanks for your answer.

So in BMT g is the absolute value of g-factor?

in Bargmann–Michel–Telegdi equation {\;\,dS^\alpha\over d\tau}={e\over m}\bigg[{g\over2}F^{\alpha\beta}S_\beta+\left({g\over2}-1\right)U^\alpha\left(S_\lambda F^{\lambda\mu}U_\mu\right)\bigg]\;, there is g-factor present. I'm a bit confused about its definition. If it is defined as...

Yes, it's the dynamics of decay of polarized particles that interests me.

Thanks Bill. Is it correct that for a polarized beam you know the spin polarization vector of particles {\bf S}=(S_x,S_y,S_z), where these components are probabilities for a measured spin to be in that direction? When a beam is scattered from a target sometimes particle's spin is also measured...

In experiments with polarized beams of particles, I suppose one knows the spin orientation probabilities of those particles, is that the case? When physicists make experiments with polarized beams of unstable particles, how do they treat spin in a decay of such a polarized particle? If the...

You can easily calculate the volume with a Monte-Carlo integration.

Dynamical system This billiard is a dynamical system for which i should construct attractors and numerically find its fractal dimensions. (http://en.wikipedia.org/wiki/Dynamical_billiards) Let's say that only the boundary is oscillating. Let mass of the particle be 1. Phase space What are the...

Homework Statement The center of a circular billiard is harmonically oscillating in horizontal direction with the amplitude a and frequency omega. Describe the motion of elastic particle with mass m in this billiard. Use the proper phase space and Poincare map. Under what conditions...
