Two protons are racing directly toward each other at the same speed. They collide, and a stationary top quark is produced. What is the minimum gamma factor each of the two protons must have for this to be possible?
The rest mass energy of Top quark should match the total energy of two protons so as to conserve energy.
To calculate the rest mass energy of the Top quark, we use the following relation.
ET0= mT0c^2
Putting in the values.
ET0=3.08×10^−25×(3×108)2
ET0= 27.7×10-9J
Where did the 3.08 x 10^-25 come from
Say that the mean lifetime of a π+ meson in its own rest frame is τ = 2.6 x 10-8 s. A pion of this lifetime is created at an altitude 100 km in the atmosphere by the collision of an incoming cosmic·ray proton with an atmospheric nucleus, and it has lifetime τ.
Find the distance between the point of creatioin and the ground (in the pion's rest frame).

(b) Atthat field magnitude, what is the kinetic energy of a proton emergingfrom the cyclotron? Suppose, instead, that B = 1.57 T. (c) Whatoscillator frequency is required to achieve resonance now?

- The K0 meson is an uncharged member of the particle “zoo” that decays into two charged pions according to K0 → π+ + π−. The pions have opposite charges, as indicated, and the same mass, mπ = 140 MeV/c2. Suppose that a K0 at rest decays into two pions in a bubble chamber in which a magnetic field of 2.0 T is present (see Fig. P2.22). If the radius of curvature of the pions is 34.4 cm, find (a) the momenta and speeds of the pions and (b) the mass of the K0 meson.arrow_forwardIf the mass-density of baryonic matter is rhoM = 10^-28 kg m^-3 and the current temperature of the cosmic microwave background is T = 2.7 K, calculate: (a) The mass-density of radiation (i.e rhoR) (b) The photon-baryon ratio (c) The temperature when rhoR = rhoMarrow_forwardThe sigma-zero particle decays mostly via the reaction Σ0 → Λ0 + γ .

- The decay of one type of K-meson is cited as evidence that nature favors matter over antimatter. Since mesons are composed of a quark and an antiquark, is it surprising that they would preferentially decay to one type over another? Is this an asymmetry in nature? Is the predominance of matter over antimatter an asymmetry?arrow_forwardEdwin Hubble observed that the light from very distant galaxies was redshifted and that the farther away a galaxy was, the greater its redshift. What does this say about very distant galaxies? When Hubble first estimated the Hubble constant, galaxy distances were still very uncertain, and he got a value for H of about 600 km/s per Mpc. What would this have implied about the age of the universe? What problems would this have presented for cosmologists?arrow_forwardWhen an electron and positron collide at the SLAC facility, they each have 50.0 GeV kinetic energies. What is the total collision energy available, taking into account the annihilation energy? Note that the annihilation energy is insignificant, because the electrons are highly relativistic.arrow_forward
- A photon with an energy of 2.09 GeV creates a p roton – antiproton pair in which the proton has a kinetic energy of 95.0 MeV. What is the kinetic energy of the antiproton?arrow_forwardAn electron cannot decay into two neutrinos. Which of the following conservation laws would be violated if it did: (a) energy, (b) angular momentum, (c) charge, (d) lepton number, (e) linear momentum, (f) baryon number?arrow_forwardThe primary decay mode for the negative pion is π− → μ− + ν-μ . (a) What is the energy release in MeV in this decay? (b) Using conservation of momentum, how much energy does each of the decay products receive, given the π− is at rest when it decays? You may assume the muon antineutrino is massless and has momentum p = E / c , justlike a photon.arrow_forward
