CP violation in the hyperon decays $Σ \to N π$

Xiao-Gang He, Xiao-Dong Ma, Jusak Tandean +1

The study of $C P$ violation in hyperon transitions has a long history. In the early 2000s the HyperCP experiment made a major effort to seek $C P$ -odd signals in the decay sequence…

An EFT toolbox for baryon and lepton number violating dinucleon to dilepton decays

Xiao-Gang He, Xiao-Dong Ma

In this paper we systematically consider the baryon ( $B$ ) and lepton ( $L$ ) number violating dinucleon to dilepton decays ($pp\to \ell^+\ell^{\prime+}, pn\to \ell^+\barν^\prime, nn\…

$Δ B = 2$ neutron decay into antiproton mode $n \to p ˉ e^{+} ν (ν ˉ)$

Xiao-Gang He, Xiao-Dong Ma

We discuss the unique baryon number violation by two units neutron decay mode $n \to p ˉ e^{+} χ$ , with $χ$ being the standard model (SM) neutrino $ν$ or antineutrino $ν ˉ$ or any…

Evading the Grossman-Nir bound with $Δ I = 3/2$ new physics

Xiao-Gang He, Xiao-Dong Ma, Jusak Tandean +1

Rare kaon decays with missing energy, $K \to π$ + $E_{miss}$ , have received considerable attention because their rates can be calculated quite precisely within the standard model (…

CP violating phase sum rule $δ_{KM}^{q} + δ_{KM}^{l} = 0$ for CKM and PMNS matrices

Junxing Pan, Jin Sun, Xiao-Dong Ma +1

The non-zero Dirac phases $δ^{q}$ and $δ^{l}$ in the CKM and PMNS mixing matrices signify CP violation. In general they are independent. Experimental data including recent T2K results…

Breaking the Grossman-Nir Bound in Kaon Decays

Xiao-Gang He, Xiao-Dong Ma, Jusak Tandean +1

The ratio $B (K_{L} \to π^{0} ν ν ˉ) / B (K^{+} \to π^{+} ν ν ˉ)$ of the branching fractions of kaon decays $K_{L} \to π^{0} ν ν ˉ$ and $K^{+} \to π^{+} ν ν ˉ$ has a maximum of about 4.3 u…
