The processes involving low energy $\bar{K}N$ and $Y\pi$ interactions (where$Y= \Sigma$ or $\Lambda$) are studied in the framework of heavy baryon chiralperturbation theory with the $\Lambda$(1405) resonance appearing as anindependent field.  The leading and next-to-leading terms in the chiral expansion are taken intoaccount. We show that an approach which explicitly includes the $\Lambda$(1405)resonance as an elementary quantum field gives reasonable descriptions of boththe threshold branching ratios and the energy dependence of total crosssections.Comment: 16 pages, 6 figure
