Fingerprinting CP-violating New Physics with B → Kμ + μ −

Journal of High Energy Physics, 2023
The B → Kℓ + ℓ − system is particularly interesting to explore physics beyond the Standard Model. Such effects could provide new sources of CP violation, thereby giving rise to Wilson coefficients which could not only be real, as assumed in most analyses,

CP Violation with Heavy Hadrons [PDF]

, 1996
I review several topics involving CP violation with heavy hadrons. In particular, I discuss (i) Hyperons: CP violation in the decay $\Lambda^0 \to p \pi^-$, (ii) Charm: indirect CP violation in the D^0 system, both within and beyond the SM, and (iii ...

CP violation in D-meson decays

EPJ Web of Conferences, 2014
Since most probably Standard Model cannot explain large value of CP asymmetries recently observed in D-meson decays the fourth quark-lepton generation explanation of it is proposed.

Complex S 3-symmetric 3HDM

Journal of High Energy Physics, 2023
CP violation plays a very important role in nature with implications both for Particle Physics and for Cosmology. Accounting for the observed matter-antimatter asymmetry of the Universe requires the existence of new sources of CP violation beyond the ...

CP violation at colliders [PDF]

, 1994
The prospects of experimental detection of $CP$ violation at $e^+e^-$ and $pp/p\overline{p}$ colliders are reviewed. After a general discussion on the quantities which can measure $CP$ violation and on the implications of the $CPT$ theorem, various ...

CP Violation [PDF]

, 1999
Abstract CP violation is an intriguing and elusive subject, and current knowledge of it remains limited, on both the experimental and theoretical levels. Researchers lack a fundamental understanding of its origin, and this is all the more important because CP violation is related to the generation problem and mass problem, two of the ...

Leptogenesis from low energy CP violation

Journal of High Energy Physics, 2019
We revisit the possibility of producing the observed baryon asymmetry of the Universe via thermal leptogenesis, where CP violation comes exclusively from the low-energy phases of the neutrino mixing matrix.

CPT and CP, an entangled couple

Journal of High Energy Physics, 2020
Even though it is undoubtedly very appealing to interpret the latest T2K results as evidence of CP violation, this claim assumes CPT conservation in the neutrino sector to an extent that has not been tested yet.

CP violation at the finite temperature

Physics Letters B, 2019
In this letter we explore the CP violation at the finite temperature. We show that a spontaneous CP-violating phase φ may arise at the temperature of the electroweak phase transition, and φ can provide a source term for generating the matter-antimatter ...

New physics in CP violation experiments [PDF]

, 2001
CP violation plays a privileged role in our quest for new physics beyond the electroweak standard model (SM). In the SM the violation of CP in the weak interactions has a single source: the phase of the quark mixing matrix (the CKM matrix, for Cabibbo ...
