    Meson build up from a quark-antiquark pair

    I have some questions about mesons. I don't really understand why they are build up from a quark-antiquark pair. I know from the theory that one can classify the mesons by considering the tensor product of the fundamental representation [3] and the representation [3'] (the prime for denoting...

    Calculate the lifetime of the theta meson

    A newly discovered Θ meson has a rest mass energy of 1020 MeV, and electric charge of 0, and a measured energy width of 4 MeV a Using the uncertainty principle, calculate the lifetime of the Θ meson b A Θ meson at rest decays into K+ and K- mesons. Find the total KE of the kaons Thanks...

    Struggling with a Physics Problem: Calculating Meson Velocities

    I've just started an introductory modern physics course, and it's making me ache a bit. I'm unsure about this problem: So, if I calculate the momentum of the two pi mesons in the rest frame of the decaying meson... well... I've gotten that far. I'm not sure if I need to transform the...

    Mass conservation in meson theory

    In the Meson theory of nuclear forces, exchange of pi meson is given by: n\rightarrow n + \pi^{0} p\rightarrow p + \pi^{0} n\rightarrow p + \pi^{-} p\rightarrow n + \pi^{+} Here the charge is conserved. But I don't understand how mass conservation takes place as in some of the cases a...

    Calculating the Lifetime of J/ψ Meson Using the Uncertainty Principle

    I'm just being introduced to particle physics and wondering if I'm going about this correct..can someone help me? thanks The measured width of the J/ψ meson is 88 keV. Estimate its lifetime. Lifetime (s) of J/ψ meson is 8E-21 s Using uncertainty principle: ΔE = h/2πΔt isolate for delta...

    Could you entangle a charmed meson?

    could you entangle a charm meson? Is it possible to entangle and teleport a charm meson? I ask this because if you could, it would be traveling faster than light (instantaniously) and if it is traveling faster than light it would have to travel in time, if we could teleport a charm meson...

    Decay of Roe Meson: Conservation Laws Explained

    I just started a class in particle physics this semester, and I really need help on one of our first homework problems. We are supposed to show that while the following decays are allowed: roe(+) --> pi(0)pi(+) roe(-) --> pi(0)pi(-) roe(0) --> pi(+)pi(-) the following decay is not...

    Charm Meson Decay & Particles Explained

    What is a charmed meson? What are eta, eta', omega, or phi particles? Is there a site which explains the charm meson decay and defines these other particles.

    Coalescence between a neutron and a K+ meson

    I think it is simply the coalescence between a neutron and a K+ meson. What are your thoughts?
