New test on contact interactions in the data at $s$ 130-207GeV by Bhabha scattering process $e^{+} e^{-} \to e^{+} e^{-}$

Zhikun Xi, Minghui Liu, Jürgen Ulbricht

We used data mainly collected by OPAL experiment to test the signal significance of a parameter $ε$ , which is equal to zero in SM. For total cross sections, we obtained n…

Utilizing Theory and Experiment to Search for new structures of Fundamental Particles

Jürgen Ulbricht, Minghui Liu

Our current understanding of the Big Bang indicates that the universe was not a dimensionless point at $t = 0$ but already had four dimensions. This work, exploring physics beyond th…
