Enhancement of Loop-induced H±w∓z0 Vertex
نویسنده
چکیده
We discuss the non-decoupling effects on the loop-induced H±W∓Z0 vertex in the general two Higgs-doublet model. The decay process H± → W±Z0 is analyzed at one-loop level and possible enhancement of the decay width is explored. We find that a novel enhancement can be realized by the Higgs non-decoupling effects with large mass difference between charged and CP-odd Higgs bosons. The branching ratio of the process can be a few % ∼ 10%. Therefore the decay mode may be detectable at LHC or future e+e− linear colliders (LC’s).

Enhancement of Loop Induced H±W∓Z0 Vertex in Two Higgs-doublet Model
The non-decoupling effects of heavy Higgs bosons as well as fermions on the loop-induced H±W∓Z0 vertex are discussed in the general two Higgs doublet model. The decay width of the process H± → W∓Z0 is calculated at one-loop level and the possibility of its enhancement is explored both analytically and numerically. We find that the novel enhancement of the decay width can be realized by the Higg...
متن کاملEdge-coloring Vertex-weightings of Graphs
Let $G=(V(G),E(G))$ be a simple, finite and undirected graph of order $n$. A $k$-vertex weightings of a graph $G$ is a mapping $w: V(G) to {1, ldots, k}$. A $k$-vertex weighting induces an edge labeling $f_w: E(G) to N$ such that $f_w(uv)=w(u)+w(v)$. Such a labeling is called an {it edge-coloring k-vertex weightings} if $f_{w}(e)not= f_{w}(echr(chr(chr('39')39chr('39'))39chr(chr('39')39chr('39'...

متن کاملDistance-based topological indices of tensor product of graphs
Let G and H be connected graphs. The tensor product G + H is a graph with vertex set V(G+H) = V (G) X V(H) and edge set E(G + H) ={(a , b)(x , y)| ax ∈ E(G) & by ∈ E(H)}. The graph H is called the strongly triangular if for every vertex u and v there exists a vertex w adjacent to both of them. In this article the tensor product of G + H under some distancebased topological indices are investiga...
متن کاملFull electroweak one - loop corrections to W + W − Z 0 production at the ILC
The precise investigation of the W+W−Z0 production at the e+e− International Linear Collider(ILC) is of crucial importance in probing the couplings between massive vector gauge bosons and discovering the signature of new physics beyond the standard model(SM). We study the full one-loop EW effects on the observables, such as, the total cross section, the differential cross section of the invaria...
