Contribution
It presents a direct construction linking mutually unbiased bases and Bell states, expanding the toolkit for quantum entanglement analysis.

A straightforward relation between mutually unbiased bases and Bell states is established
The properties of the new generalized Bell states are analyzed in detail
Abstract
We employ a straightforward relation between mutually unbiased and Bell bases to extend the latter in terms of a direct construction for the former. We analyze in detail the properties of these new generalized Bell states, showing that they constitute an appropriate tool for testing entanglement in bipartite multiqudit systems.
