superfield directly couples to messengers whereas the top superfields do not, relatively light stop in natural SUSY can be easily obtained as we can have the small stop soft mass from the effect explained above and the large LR mixing from large A term. $A/m^2$ problem appears in $H_u$ soft terms such that large $A$ term at the same time generate large $m_{H_u}^2$ at the messenger scale and it can make the electroweak symmetry breaking difficult. It is analogous to the famous $\mu/B\mu$ problem in gauge mediation. To avoid this but to allow the large $\lambda$ for maximal mixing, large $-c_2 \lambda^2 g^2$ part in $m_{H_u}^2$ is required. This can be achieved by introducing new gauge bosons or making strong interaction involved [@Kang:2012ra]. On the other hand, one loop, negative contribution to $m_{H_u}^2$ can be considered if the messenger scale is low as analysed in detail in [@Craig:2012xp].

![ Higgs mass as a function of $y_{\nu}$ for $B_N = 5  \times 10^{5} {\,\textrm{GeV}}$, $\rho = 0.1$. Higgs mass can be achieved with the help of Yukawa mediation for large $\tan \beta$ region. At $y_{\nu} \sim 0.7$, stop mass is approximately $1 {\,\textrm{TeV}}$. []{data-label="fig:Higgsmass"}](YHiggsMass.eps){width="70.00000%"}
