Description
We present preliminary results for the kaon semileptonic form factors
using one of the PACS10 configuration sets, whose physical volume is
(10.2 fm)$^4$ at the physical point with the lattice spacing of 0.064 fm.
The configuration was generated using the Iwasaki gauge action and $N_f=2+1$
stout-smeared clover quark action. The value of |$V_{us}$| is determined
using the interpolated result of the form factors to the zero momentum
transfer. Our value of |$V_{us}$| is compared with a prediction of the standard
model from the unitarity triangle and recent lattice results.
We also show a preliminary result of |$V_{us}$| in the continuum limit
obtained from analysis using the preliminary result of 0.064 fm combined
with our previous result at the coarser lattice spacing of 0.085 fm.
