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…

Revisiting models that enhance $B^{+} \to K^{+} ν ν ˉ$ in light of the new Belle II measurement

Xiao-Gang He, Xiao-Dong Ma, German Valencia

Belle II has recently reported the new measurement $B (B^{+} \to K^{+} ν ν ˉ) = (2.3 \pm 0.7) \times 1 0^{- 5}$ \cite{Belle-II:2023esi} which is two times larger than their previous resu…

A Search for Light Fermionic Dark Matter Absorption on Electrons in PandaX-4T

Dan Zhang, Abdusalam Abdukerim, Zihao Bo +89

We report a search on a sub-MeV fermionic dark matter absorbed by electrons with an outgoing active neutrino using the 0.63 tonne-year exposure collected by PandaX-4T liquid xenon…

Revisiting the Fermionic Dark Matter Absorption on Electron Target

Shao-Feng Ge, Xiao-Gang He, Xiao-Dong Ma +1

We perform a systematic study of the fermionic DM absorption interactions on electron target in the context of effective field theory. The fermionic DM absorption is not just sensi…

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…
