# BSM Kaon Mixing at the Physical Point

## TL;DR

This paper reports new preliminary lattice QCD results for BSM kaon mixing parameters at the physical point, using domain wall fermions with 2+1 flavors, improving accuracy by simulating near physical pion and kaon masses.

## Contribution

It provides the first results for bag parameters and operator ratios at the physical point with domain wall fermions, enhancing the precision of kaon mixing studies.

## Key findings

- Results obtained at the physical pion and kaon masses.
- Comparison with previous heavier quark simulations.
- Improved accuracy in BSM kaon mixing parameters.

## Abstract

We present new preliminary results for bag parameters and ratios of the BSM kaon mixing operators measured at the physical point. The results are obtained from simulations of domain wall fermion QCD with 2+1 flavours with an Iwasaki gauge, and now include pion and kaon masses very close to the physical point. We compare these results to our collaboration's previous results obtained from heavier simulated quarks.
