Query: $\Sigma_cN$ interaction in chiral perturbation theory   We adopt the heavy baryon chiral perturbation theory to calculate the
$\Sigma_cN$ interaction to the next-to-leading order. We consider the contact
interactions, one-pion-exchange contributions, two-pion-exchange diagrams, and
renormalization effects of the vertices, masses and wave functions. With the
pion mass dependent expression, we fit the $\Sigma_cN$ interaction from HAL QCD
calculation with $m_{\pi}\approx 410$ MeV and $m_{\pi}\approx 570$ MeV, and
then extrapolate it to the physical pion mass. The $^3S_1(I=1/2)$ $\Sigma_{c}N$
interaction is weakly attractive but no bound solution is found. We also
propose a quark model to estimate the leading order $\Sigma_cN$ contact
interaction with the $NN$ interaction as input. This approach combining the
quark model and the chiral effective field theory predicts a very attractive
interaction in $^1S_0(I=3/2)$ $\Sigma_{c}N$ channel and a two-body bound state.
