Triple-product asymmetries in , , and decays

M Gronau, JL Rosner - Physical Review D—Particles, Fields, Gravitation, and …, 2011 - APS
One distinguishes between “true” CP-violating triple-product (TP) asymmetries which require
no strong phases and “fake” asymmetries which are due to strong phases but require no CP …

Probing violation systematically in differential distributions

G Durieux, Y Grossman - Physical Review D, 2015 - APS
We revisit the topic of triple-product asymmetries which probe CP violation through
differential distributions. We construct distributions with well-defined discrete symmetry …

Measurement of Polarization and Search for Violation in Decays

T Aaltonen, B Álvarez González, S Amerio, D Amidei… - Physical review …, 2011 - APS
We present the first measurement of polarization and CP-violating asymmetries in a B s 0
decay into two light vector mesons, B s 0→ ϕ ϕ, and an improved determination of its …

Searching for new physics with penguin decays

B Bhattacharya, A Datta, M Duraisamy, D London - Physical Review D …, 2013 - APS
We present the most general (six-helicity) angular analysis of B s 0→ V 1 (→ P 1 P 1′) V 2
(→ P 2 P 2′)(V i is a vector meson, and P i, P i′ are pseudoscalars). We focus on final …

Study of decays in the perturbative QCD approach

Y Li, DC Yan, Z Rui, ZJ **ao - The European Physical Journal C, 2021 - Springer
In this work, we provide estimates of the branching ratios, direct CP asymmetries and triple
product asymmetries in B_ (s) → (π π)(K π) B (s)→(π π)(K π) decays in the perturbative QCD …

Possible large violation in charmed decays

YF Shen, JP Wang, Q Qin - Physical Review D, 2023 - APS
We propose that the cascade decay Λ b→ D (→ K+ π-) N (→ p π-) may serve as the
discovery channel for baryonic CP violation. This decay chain is contributed by, dominantly …
