We consider the photon mediated processes as well as the gluon-gluon fusion (ggF), photon-proton interactions, and Vector Boson Fusion (VBF) processes to produce the RHNs.

In [4], it was shown that the spectrum required to generate the excess naturally arises in the string derived model of [5], which allows for a light Z' vector boson. Anomaly cancellation mandates that the mass scale of the Standard Model singlet state, which is produced in resonance in Figure 1, as well as the mass scale of the heavy vector-like states that are used in the production and decay of the singlet states, be the Z' symmetry breaking scale.
Secondly, with the definition on branching ratios [mathematical expression not reproducible], where [mathematical expression not reproducible] (X is a SM fermion or vector boson), Br([h.sub.2] [right arrow] [V.sub.i][V.sub.i]) depends on the magnitude of [GAMMA]([h.sub.2] [right arrow] [h.sub.1][h.sub.1]) relative to [GAMMA]([h.sub.2] [right arrow] XX).
The contribution of new heavy quarks to vector boson coupling may be compensated by the contribution of 50 GeV neutrino [19-21]; however, such assumption seems artificial.
A good description of the first excited positive and negative parity bands of nuclei in the rare earth and the actinide region has achieved [2-4] using the interacting vector boson model.

In the framework of the standard Heisenberg uncertainty principle, the Hawking radiation of the new-type black holes had been studied by using the quantum tunneling process of the scalar, Dirac, and vector boson particles [23, 36].
Jets with high-[eta]mainly come from the vector boson fusion topologies.
At the LHC these pNG states most effectively occur in two ways: in vector boson fusion (VBF) reaction pp [right arrow] [V.sup.*][V'.sup.*] [right arrow] [??][??]', where V = W,Z,y, or in the s-channel of qq - or qqfusion--Drell-Yan type (DYT) process, pp - V'* - Jin.
