We present a minimal extensions of Standard Model with TeV scale vector like fermions which leads to unification of gauge couplings. Model has been constraints from proton decay, Higgs stability and perturbativity. The simplest models contain copies of vector like fermions in two different (incomplete) representations. Some models enclose SU(2) triplet, Type III seesaw mechanism for neutrino masses whereas some others have a dark matter candidate. In all the models, at least one of the candidates has non-trivial representation under SU(3):color. In the limit of vanishing Yukawa couplings, new QCD bound states are formed, which can be probed at LHC. The present limits based on results from 13 TeV already probe these particles for masses around a TeV. © Springer Nature Singapore Pte Ltd 2020.
