p-Adic description of Higgs mechanism V: New Physics
  TGD suggests the existence of two new branches of physics, namely M_{89} hadron physics and M_{127} leptohadron physics. Leptons and U type quarks are predicted to have light colored excitations. The anomalous production of e^+e^- pairs in heavy ion collisions sup- ports the existence of light leptomeson but there are objections against light exotics. a) Asymptotic freedom in the standard sense might be lost: the recently identified exotic color bosons however save the situation. b) Z^0 decay width seems to exclude light exotics. The solution of the problem relies on p-adic probability concept. The real counterpart (\sum_jP(ito j))_R for the sum of p-adic probabi- lities differs from the sum \sum_j P(i toj)_R for the real counter- parts of p-adic probabilities. Interpretation:(\sum_jP(i to j))_R is used, when only a common signature for final states is used. \sum_j(P(i to j)_R is used, when each final state is monitored separately. The total decay rate of $Z^0$ to unmonitored exotic leptons is sensitive to the value of \theta_W(eff) and vanishes for sin^2(\theta_W(eff))=0.2324 and sensible value of \alpha_s(L)! In TGD the observed top quark candidate most probably corresponds to u and d quarks of M_{89} hadron physics. The details of the identification and signatures of the new Physics are discussed.
