We discuss the necessity and feasibility of BSM THC measurements at current and future colliders.
In this talk CEPC general status will be reported including CEPC accelerator EDR progress, CEPC detector reference design report, CEPC civil engineering design progress, CEPC industrial preparation, CEPC international collaboration and the preparation for the CEPC submission to China's 15th five year plan.
We demonstrate for the first time that new physics explaining the long standing charged $B$ meson anomalies, $R(D^{(*)})$, can be the source of CP violation that explains the observed baryon asymmetry of the universe (BAU). We consider the general two Higgs doublet model with complex Yukawa couplings and compute the BAU in the semiclassical formalism, using a novel analytic approximation for...
The Next-to-Two-Higgs-Doublet model (N2HDM) has a rich vacuum structure where multiple electroweak (EW) breaking minima, as well as CP and electric-charge breaking minima, can coexist. These minima can be deeper than the electroweak vacuum $v_{ew} \approx 246$ GeV of our universe, making our vacuum metastable. In such a case, one needs to calculate the tunneling rate from the EW vacuum to the...
With the development on canonical differential equation, integral basis with uniformal transcendental weights, computational algebraic geometry method, the era of analytic computations of multi-loop multi-leg multi-scale Feynman integrals is coming. We analytically computed all 2loop 6point planar massless Feynman integrals. This is a mile stone of analytic feynman integral computation. The...
In this talk, we will discuss the prospects of testing quantum entanglement effects and Bell inequalities at future Higgs factories, as well as explore the potential of using these investigations to search for new physics beyond the Standard Model.
