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?
A virtual particle having an approximate mass of 1014 GeV/c2 may be associated with the unification of the strong and electroweak forces. For what length of time could this virtual particle exist (in temporary violation of theconservation of mass-energy as allowed by the Heisenberg uncertainty principle)?
Calculate the mass in GeV/c2 of a virtual carrier particle that has a range limited to 10−30 m by the Heisenberg uncertainty principle. Such a particle might be involved in the unification of the strong and electroweak forces.
The quark flavor change d → u takes place in β− decay. Does this mean that the reverse quark flavor change u → d takes place in β+ decay? Justify your response by writing the decay in terms of the quark constituents, noting that it looks as if a proton is converted into a neutron in β+ decay.
According to thermodynamic equilibrium, which should be the most abundant and least abundant quarks during the period from 10-13 s to 10 -3 s?
If 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 = rhoM
What mechanism can simultaneously solve both the flatness and horizon problems in cosmology?
What effect does increasing the interaction strength of a massive particle species haveon its thermal relic abundance if it was in thermal equilibrium in the early universe(assuming no initial asymmetry)? a. relic abundance increases b. relic abundance decreases c. relic abundance essentially unchanged d. not enough information
What is the electrical charge of the baryons with the quark compositions (a) uud- and (b)udd? What are these baryons called?
