Ultraviolet fixed point and massive composite particles in TeV scales
Abstract
We present a further study of the dynamics of high-dimension fermion operators attributed to the theoretical inconsistency of the fundamental cutoff (quantum gravity) and the parity-violating gauge symmetry of the standard model. Studying the phase transition from a symmetry-breaking phase to a strong-coupling symmetric phase and the -function behavior in terms of four-fermion coupling strength, we discuss the critical transition point as a ultraviolet-stable fixed point where a quantum field theory preserving the standard model gauge symmetry with composite particles can be realized. The form-factors and masses of composite particles at TeV scales are estimated by extrapolating the solution of renormalization-group equations from the infrared-stable fixed point where the quantum field theory of standard model is realized and its phenomenology including Higgs mass has been experimentally determined. We discuss the probability of composite-particle formation and decay that could be experimentally verified in the LHC by measuring the invariant mass of relevant final states and their peculiar kinetic distributions.

Comments
Both theoretical parts and in particular the predictions in experimental part have been clarified. Beside, the discussions on the lepton sector in the previous version (v1) have seen removed due to the length limit of the Letter, and will be submitted to elsewhere. The version (v2) reproduces the version (v1). I have corrected this error and the version (v3) should be final as appeared in PLB
