  • Mesons: Particles of the Subatomic World • Physics Forums
    The discussion centers around mesons, their properties, and their roles in particle physics, particularly in relation to the strong force and nuclear interactions Participants explore definitions, characteristics, and theoretical implications of mesons, including specific types like pions and kaons, as well as their interactions within atomic nuclei Some participants define mesons as
  • Particle Physics: Why are Mesons a type of Gauge Boson?
    The discussion revolves around the classification of mesons in particle physics, specifically questioning why mesons, which are hadrons composed of a quark and an anti-quark, are considered a type of gauge boson The scope includes theoretical aspects of particle classification and properties related to spin Some participants assert that mesons are bosons due to their composite nature and
  • Whats the reason behind the existence of mesons?
    The discussion revolves around the existence of mesons, specifically focusing on the mechanisms that allow quark-antiquark pairs to form bound states instead of annihilating immediately
  • Why Dont Neutral Mesons Annihilate Immediately?
    The discussion centers on the behavior of neutral mesons, specifically the pi neutral meson, which consists of a quark (such as up) and its corresponding anti-particle (such as anti-up) Despite being composed of particle-antiparticle pairs, these mesons do not immediately annihilate due to their short-lived bound states The analogy with positronium, where an electron and positron form a
  • Psuedoscalar Mesons - why is there an eta and an eta prime?
    The mesons are states obtained by combining quarks and antiquarks, i e states These states lie in the direct product of the and the representation spaces But this space separates into an octet and a singlet, , so the mesons consist of the octet (the pions, the kaons and the ) and the singlet (the )
  • Upsilon Meson Decays and B Meson Decays: Feynman Diagrams and Distance . . .
    The discussion revolves around the decays of Upsilon mesons and B mesons, focusing on Feynman diagrams, decay mechanisms, and the distances traveled by these particles Participants explore the reasons behind the suppression of certain decay channels and the implications of weak interactions in B meson decays Exploratory, Conceptual clarification, Assumption checking Participants discuss
  • Why Dont Quarks and Antiquarks Annihilate Each Other in Mesons?
    The discussion revolves around several fundamental questions related to particle physics, specifically focusing on mesons, the strong force, neutrinos, and the concept of spin Participants explore these topics within the context of the standard model of particle physics One participant asks why mesons, composed of a quark and an antiquark, do not annihilate each other, suggesting that they
  • Hadron interaction via strong yet k mesons decay through weak
    For example, K mesons cannot decay through the electromagnetic interaction or the strong interaction, because the electromagnetic and strong interaction both conserve strange quark number The weak interaction can violate conservation of strangeness and therefore K mesons can decay through the weak interaction, and only through the weak
  • O Physics: K Meson Decay and Velocity Calculation
    The discussion centers on the decay of a K meson with a total energy of 890 MeV into two π mesons To determine the speed of the K meson in the laboratory frame prior to decay, one must apply principles of conservation of energy and momentum The rest masses of the K meson and π mesons are crucial for solving the problem, as they affect the velocities and energies of the resulting π mesons
  • Time Dilation Problem with Mesons - Physics Forums
    Mesons leave this target with nearly the speed of light If there were no time stretching and if no mesons were removed from the resulting beam by collisions, what would be the greatest distance from the target at which half of the mesons would remain undecayed b) The mesons of interest in a particular experiment have a speed of 9978 that of
