Why the semi-leptonic decays of mesons involving neutrinos are consider as clean signal for new Physics. As for as I think these are free from hadronic complexities (because we do not know exactly about strong interactions) and electromagnetic interference (because neutrinos do not couple to...

I am confuse about the dimension of an operator? Why we need an operator of Dim six or greater for new physics?

what is the difference between luminosity, Intensity and flux in particle physics? Some time people use them in similar meanings.

Is there any relationship between phase space and entropy? regarding to decay of particles

what are standards model limits on decay of K0, Do, B0 meson into a pair of neutrino and anti neutrino. I know that these highly suppressed due to involve FCNC. but if someone can tell me about theoretical limits on these reactions.

how the spin is associated with a particle. is there a difference in spin for charge particle and a neutral particle, i mean difference in spin due to charge or spin is independent of charge. what is procedure to assign spin to a particle? p help.

so simple. thanks. but is this possible with charge particle?

is this possible for a masive particle to take retilinier path in a non uniform electric field

why there is a need for a new type of parity? is cpt voilated in supersymmetry

what is R Parity and why?

particle and antiparticle compeletly annihilate each other. Is this possible in case of proton and electron? So there are some other differences, not just charge

thanks is it violated only in weak intractions only

What is Cp-violation

may someone tell me what is a suprerspace? thanks

i do not think so.it will better if you ask in what sense you are asking this?
