A Grand-Unified Nelson-Barr Model
Jakob Schwichtenberg, Paul Tremper, Robert Ziegler
We argue that the Nelson-Barr solution to the Strong CP Problem can be naturally realized in an E Grand-Unified Theory. The chiral SM fermions reside in three generations of E$…
Direct CP violation in decays and supersymmetry
Teppei Kitahara, Ulrich Nierste, Paul Tremper
The quantities and measure the amount of direct and indirect CP violation in decays, respectively. Using the recent lattice results from the RBC and UK…
Recent progress on CP violation in decays in the SM and a supersymmetric solution
Teppei Kitahara, Ulrich Nierste, Paul Tremper
Using the recent first lattice results of the RBC-UKQCD collaboration for decays, we perform a phenomenological analysis of and find a discrepancy bet…
Singularity-free Next-to-leading Order Renormalization Group Evolution and in the Standard Model and Beyond
Teppei Kitahara, Ulrich Nierste, Paul Tremper
The standard analytic solution of the renormalization group (RG) evolution for the Wilson coefficients involves several singularities, which complicate analytic solutions.…
Supersymmetric Explanation of CP Violation in Decays
Teppei Kitahara, Ulrich Nierste, Paul Tremper
Recent progress in the determination of hadronic matrix elements has revealed a tension between the measured value of , which quantifies direct violation in…
