We present a comprehensive model independent analysis of all breaking patterns resulting from ∆(96) ⋊ $\textit{H}$ in the tri-direct CP approach of the minimal seesaw model with two right-handed neutrinos. The three generations of left-handed lepton doublets are assumed to transform as the irreducible triplet of ∆(96), and the two right-handed neutrinos are assigned to singlets. In the case that both flavon fields $\textit{ϕ}$ and $\textit{ϕ}$ transform as triplet $$ {\overline{\textbf{3}}}_{\textbf{0}} $$ , only one phenomenologically viable lepton mixing pattern is obtained for normal ordering neutrino masses. The lepton mixing matrix is predicted to be the TM1 pattern, with neutrino masses, mixing angles, and CP violation phases depending on only three real input parameters. When $\textit{ϕ}$ is assigned to the $$ {\overline{\textbf{3}}}_{\textbf{1}} $$ representation, an additional real parameter $\textit{x}$ must be included. Then we find 42 (12) independent phenomenologically interesting mixing patterns for normal (inverted) ordering neutrino masses, and the corresponding predictions for lepton mixing parameters and neutrino masses are obtained. Furthermore, we perform a detailed numerical analysis for five (one) example breaking patterns with some benchmark values of $\textit{x}$ for normal (inverted) ordering. For the five normal examples, the absolute values of the first columns of the PMNS matrix are fixed to be $$ {\left(\sqrt{\frac{2}{3}},\frac{1}{\sqrt{6}},\frac{1}{\sqrt{6}}\right)}^T $$ , $$ \frac{1}{5}{\left(\sqrt{17},2,2\right)}^T $$ , $$ \frac{1}{\sqrt{38}}{\left(5,2,3\right)}^T $$ , $$ \frac{1}{\sqrt{57}}{\left(\sqrt{37},\sqrt{10},\sqrt{10}\right)}^T $$ and $$ \frac{1}{3}{\left(\sqrt{6},1,\sqrt{2}\right)}^T $$ , respectively. For the inverted example, the absolute value of the third column of the PMNS matrix is $$ \frac{1}{2\sqrt{11}}{\left(1,5,3\sqrt{2}\right)}^T $$ .

Neutrino mixing parameters and masses from ∆(96) ⋊ $\textit{H}$

A study of $$ {\Lambda}_b^0 $$ and $$ {\Xi}_b^0 $$ baryon decays to the final states $$ p{K}_{\textrm{S}}^0{\pi}^{-} $$ and $$ p{K}_{\textrm{S}}^0{K}^{-} $$ is performed using $\textit{pp}$ collision data collected by the LHCb experiment, corresponding to an integrated luminosity of 9 fb . The decays $$ {\Lambda}_b^0\to p{K}_{\textrm{S}}^0{K}^{-} $$ and $$ {\Xi}_b^0\to p{K}_{\textrm{S}}^0{K}^{-} $$ are observed for the first time, with significances reaching eight standard deviations. The branching fractions and integrated $\textit{CP}$ asymmetries are measured for the $$ {\Lambda}_b^0\to p{K}_{\textrm{S}}^0{\pi}^{-} $$ , $$ {\Lambda}_b^0\to p{K}_{\textrm{S}}^0{K}^{-} $$ , and $$ {\Xi}_b^0\to p{K}_{\textrm{S}}^0{K}^{-} $$ decays. For the decay $$ {\Lambda}_b^0\to p{K}_{\textrm{S}}^0{\pi}^{-} $$ , the $\textit{CP}$ asymmetries are measured in different regions of the Dalitz plot. No evidence of $\textit{CP}$ violation is observed.

Measurement of branching fractions and $\textit{CP}$ asymmetries in $$ {\varLambda}_b^0\left({\varXi}_b^0\right)\to p{K}_{\textrm{S}}^0{h}^{-} $$ decays

The CP properties of the Higgs boson are studied in the vector-boson fusion production mode. The analysis exploits the decay mode of the Higgs boson into two $\textit{τ}$-leptons using 140 fb of proton-proton collision data at $$ \sqrt{s}=13 $$ TeV collected by the ATLAS experiment at the Large Hadron Collider. Results are obtained using the Optimal Observable method. CP-violating interactions between the Higgs boson and electroweak gauge bosons are considered in the effective field theory framework, with the interaction strength described in the HISZ basis by $$ \overset{\sim }{d} $$ , and in the Warsaw basis by $$ {c}_{H\overset{\sim }{W}} $$ , $$ {c}_{H\overset{\sim }{B}} $$ , and $$ {c}_{H\overset{\sim }{W}B} $$ . No deviations relative to the Standard Model are observed, and limits are obtained on the strength parameters. The $$ \overset{\sim }{d} $$ parameter is constrained to the interval [−0$\textit{.}$012$\textit{,}$ 0$\textit{.}$044] at the 95% confidence level while $$ {c}_{H\overset{\sim }{W}} $$ is constrained to [−0$\textit{.}$24$\textit{,}$ 0$\textit{.}$83], when considering both linear and quadratic effects of physics beyond the Standard Model.
