Dimension Four Wins the Same Game as the Standard Model Group    [PDF]

H. B. Nielsen

In a previous article Don Bennett and I looked for,found and proposed a game in which the Standard Model group $S(U92)\times U(3))$ gets singled out as the "winner". Here I propose to extend this "game" to construct a corresponding game between different potential space time dimensions for space time. The idea is to formulate how the same competition as the one between the potential gauge groups would run out, if restricted to the potential Lorentz or Poincare groups achievable for different dimensions of space time d. The remarkable point is that it is the experimental dimension of space time 4 which wins! So the same function defined over Lie groups seems to single out both the gauge group and the space time dimension in nature. This seems a rather strange coincidence unless there is really some similar physics behind.
