	abstract = {The first spectro-polarimetric analysis of the transient NS-LMXB XTE J1701\$-\$462 has been carried out using IXPE, NICER and NuSTAR data during its 2022 outburst. We report the significant detection of energy-dependent polarization in the X-ray signal from the source on 2022 September 29 in the \$2-4\$ keV, \$4-8\$ keV and \$2-8\$ keV energy bands with a polarization degree of 3.9 \${\textbackslash}pm\$ 0.3\% (10.7\${\textbackslash}sigma\$), 5.5 \${\textbackslash}pm\$ 0.6\% (9.1\${\textbackslash}sigma\$) and 4.5 \${\textbackslash}pm\$ 0.4\% (12.6\${\textbackslash}sigma\$), respectively. The polarization angle in the overall \$2-8\$ keV band was found to be \${\textbackslash}sim 143{\textasciicircum}\{{\textbackslash}circ\}{\textbackslash}pm 2{\textasciicircum}\{{\textbackslash}circ\}\$. The spectra were modelled using a combination of thermal emission from an accretion disc, Comptonized emission from the corona and a Gaussian line. From spectro-polarimetric analysis, the polarization degree due to the disc emission was found to have an upper limit of \${\textbackslash}sim\$ 6\%, and that of the Comptonized emission was constrained at \${\textbackslash}sim\$ 10.5\${\textbackslash}pm\$4.9\% (at the 3\${\textbackslash}sigma\$ level). The implication of these results on the coronal geometry and emission mechanisms is discussed.},
