A new metric structure of the discretized Kaluza-Klein theory can give us new knowledge about extra-dimension. It can provide the new predictions of the top quark and Higgs mass that studied by Viet [15, 16] in another model. Compare the results of two approaches we can see that the new model is more agreement with experimental data. | VNU Journal of Science Mathematics Physics Vol. 36 No. 2 2020 55-65 Original Article Prediction of the Higgs and Top Quark Masses by Discrete Dimensions Revisited Nguyen Van Dat2 Nguyen Ai Viet1 2 Pham Tien Du3 1 VNU Information Technology Institute Vietnam National University Hanoi 144 Xuan Thuy Hanoi Vietnam 2 Faculty of Physics VNU University of Science Vietnam National University Hanoi 334 Nguyen Trai Hanoi Vietnam 3 Faculty of Physics Thuy Loi University 175 Tay Son Hanoi Vietnam Received 20 November 2019 Accepted 02 March 2020 Abstract A new metric structure of the discretized Kaluza-Klein theory can give us new knowledge about extra-dimension.

Introduction In physics predictions usually are based on the differential equations. The profound essence of those is the derivative which relates the value of a quantity at a given point to the one in its infinitesimal neighborhood. One of most important theoretical construction tool for unified theories is the multi-dimensional space-time. The extra dimension introduces a new variable to relate different physical theories. The derivative in the additional dimension can lead to new predictions. One example is the Kaluza-Klein theory which unifies gravity and electromagnetism 1 2 . This theoretical framework can predict massive modes charge quantization and interesting physical relations. Today this idea is already a de facto standard in physics to construct the unified theories such as string supergravity super Yang-Mills ones. ____ Corresponding author.
