Hello, I have a question about coincidence event. Let us take the decay of deuteron to proton and alpha particle, (d, pα). p and α goes in opposite direction. So, if we put two detectors in opposite directions, one of them will detect p and another will detect α simultaneously (within a small...

I found one. For someone who also need this: "Elementary Theory of Angular Momentum" by M. E. Rose.

Hi, Is there any good books which explain/calculate Wigner rotation, tensor operator, two-particle helicity state and related stuff in detail? Thanks.

Any idea?

Any body?

Hi guys, Does anybody know good references for the distribution of virtual photon, i.e. Q2 distribution, in eletro-production with fixed electron energy on a fixed target? Thanks PS: title should be "distribution of virtual photon"

Hi, How can I pass command line argument in FORTRAN 77, like in C/C++? Thanks.

Major decay mode of \lambda are \lambda \rightarrow p \pi^{-} \text{and} ~\lambda \rightarrow n \pi^{0}. These are weak decays, and \hat{H}_{EM} and \hat{H}_{W} are reffered in these cases.

Dear all, I have a fundamental question about breaking the Hamiltonian. Here is the description: Suppose a particle, \lambda^{0}, is produced in a high energy nuclear collision with proton beam. It is produced by strong interaction, and it has fixed energy (can be obtained from its...

Thanks bcrowell, I found it on google. By the way, I found that this is not the true translation of the original paper. Some paragraphs related with expansion constant (Hubble constant) are missing. And Hubble got the credit for this, which was originally shown by G. Lemaitre [Nature 479...

Hi guys, Where can I find english version of G. Lemaitre's paper Ann. Soc. Scient. bruxelles A47, 49(1927), and Ann. Soc. Scient. bruxelles A53, 51(1927) . I can find only french version in google, and I don't know french. Our library does not have this journal. Thanks.

Thanks.

Here are more lines: "The various classes of fundamental interactions are characterized by coupling constants that differ in many orders of magnitude. The electromagnetic coupling is characterized by the well-known dimensionless constant 1/137. The analogous dimensionless constant that...

Any body home?

Hi, I was reading Sakurai's "Invariance Principles and Elementary particles". In first chapter, second paragraph (page 3), there is a line "The analogous dimensionless constant that characterizes the gravitational repulsion between two protons is ...". Any body likes to comment on this, why...
