Double lepton polarization in image decay in the Standard Model with fourth generations scenario Original Research Article

This study investigates the influence of the fourth generation quarks on the double lepton polarizations in image decay by taking image with phase image. We will try to obtain a constrain on the mass of the 4th generation top like quark image, which is consistent with the image rate. With the above mentioned parameters, we will try to show that the double lepton (image) polarizations are quite sensitive to the existence of fourth generation. It can serve as a good tool to search for new physics effects, precisely, to search for the fourth generation quarks (image) via its indirect manifestations in loop diagrams.
