On the Importance of Rare Kaon Decays: A Snowmass 2021 White Paper

Jason Aebischer, Andrzej J. Buras, Jacky Kumar

We stress the importance of precise measurements of rare decays $K^{+} \to π^{+} ν ν ˉ$ , $K_{L} \to π^{0} ν ν ˉ$ , $K_{L, S} \to μ^{+} μ^{-}$ and $K_{L, S} \to π^{0} ℓ^{+} ℓ^{-}$ for the sea…

Anomalous dimensions from Yukawa couplings in SMNEFT: four-fermion operators

Alakabha Datta, Jacky Kumar, Hongkai Liu +1

The Standard Model Neutrino Effective Field Theory (SMNEFT) is the Standard Model Effective Field Theory (SMEFT) augmented with right-handed neutrinos. Building on our previous wor…

CP Violation in Rare Lepton-Number-Violating $W$ Decays at the LHC

Fatemeh Najafi, Jacky Kumar, David London

Some models of leptogenesis involve a quasi-degenerate pair of heavy neutrinos $N_{1, 2}$ whose masses can be small, $O (GeV)$ . Such neutrinos can contribute to the rare lepton…

Anomalous dimensions from gauge couplings in SMEFT with right-handed neutrinos

Alakabha Datta, Jacky Kumar, Hongkai Liu +1

Standard Model Neutrino Effective Field Theory (SMNEFT) is an effective theory with Standard Model (SM) gauge-invariant operators constructed only from SM and right-handed neutrino…

The role of non-universal $Z$ couplings in explaining the $V_{u s}$ anomaly

Ashutosh Kumar Alok, Amol Dighe, Shireen Gangal +1

The tension among measurements of $V_{u s}$ from different channels, the so-called Cabibbo Angle Anomaly, can be interpreted as a signal of lepton flavor universality (LFU) violatio…

SMEFT ATLAS of $Δ F = 2$ Transitions

Jason Aebischer, Christoph Bobeth, Andrzej J. Buras +1

We present a model-independent anatomy of the $Δ F = 2$ transitions $K^{0} - K ˉ^{0}$ , $B_{s, d} - B ˉ_{s, d}$ and $D^{0} - D ˉ^{0}$ in the context of the Standard Model Effective Field Theo…
