Phenomenological Aspects of R-parity Violating Supersymmetry with A Vector-like Extra Generation

TL;DR

This paper explores how R-parity violating supersymmetry with an extra vector-like generation can naturally produce the correct neutrino spectrum, elevate the Higgs mass to 125 GeV, and predict new heavy fermions observable at the LHC.

Contribution

It provides a detailed phenomenological analysis showing that vector-like quarks and trilinear couplings can address neutrino masses and Higgs mass without heavy superpartners.

Findings

Correct neutrino spectrum achieved via trilinear couplings.

Higgs mass raised to 125 GeV with vector-like quarks.

Predictions of new heavy fermions at LHC.

Abstract

Phenomenological analysis to the R-parity violating supersymmetry with a vector-like extra generation is performed in detail. It is found that, via the trilinear couplings, the correct neutrino spectrum can be obtained. The Higgs mass rises to 125 GeV by new up-type Yukawa couplings of vector-like quarks with no need of very heavy superpartners. Phenomena of new heavy fermions at LHC are predicted.
