Description
The slope of nucleon mass with respect to the dynamical strange quark mass
is directly related to the strange quark content of nucleon
($\langle N | \bar{s}s | N \rangle $).
This slope can be calcuated by shifting of dynamical strange quark mass
via reweighting on dynamical ensembles, which
allows a relatively inexpensive evaluation of the quantity without direct
evaluation of disconnected diagrams.
Calculation of $\langle N | \bar{s}s | N \rangle $ on
$a^{-1} \sim$ 1.7 and 2.3 Gev
(2+1) flavor dynamical Domain Wall Fermion ensembles RBC/UKQCD
collaborations generated are reported.
