Anisotropic Flow of Strange Hadrons in Relativistic Heavy-ion Collisions Measured with HADES

In this contribution, the ongoing analysis of the anisotropic flow of strange hadrons (\(K^\pm \), \({\mit \Lambda }\)) emitted from the Ag+Ag collisions at a beam kinetic energy of 1.58 GeV per nucleon is presented. The anisotropic flow is expressed with the Fourier coefficients of the \(1^\mathrm {st}\) and \(2^\mathrm {nd}\) order, corresponding to the directed and elliptic flow, respectively. However, only the \(v_1\) distribution is shown due to statistical limitations. The directed flow of \(K^+\) has a negative slope in the low-\(p_{\mathrm {t}}\) region, opposite to protons, while the \(v_1\) slope of \({\mit \Lambda }\) is similar to that of the protons regardless of momentum.
