      abstract     = {Semiflexible polymers comprised of active Brownian
                      particles (ABPOs) exhibit intriguing activity-driven
                      conformational and dynamical features. Analytically, the
                      generic properties of ABPOs can be obtained in a mean-field
                      description applying the Gaussian semiflexi- ble polymer
                      model. In this article, we derive a path integral
                      representation of the stationary-state distribution function
                      of such ABPOs, based on the stationary-state distribution
                      function of the normal mode amplitudes following from the
                      Langevin equation of motion. The path integral includes
                      characteristic semiflexible polymer contributions from
                      entropy and bending energy, with activity depen- dent
                      coefficients, and, in addition, activity-induced torsional
                      and higher order correlations along the polymer contour.
                      Focusing on a semiflexible polymer approximation, we
                      determine various properties such as the tangent-vector
                      correlation function, effective persis- tence length, and
                      the mean-square end-to-end distance. The latter reflects the
                      characteristic features of ABPOs, and good quantitative
                      agreement is obtained with the full solution for larger
                      activities, specifically for flexible polymers. Moreover,
                      the approximation indi- cates the relevance of torsional and
                      higher order contour correlations for the ABPO
                      conformations. In general, the ABPO path integral
                      illustrates how colored noise (active fluctuations) affects
                      semiflexible polymer conformations in comparison to white
                      noise thermal fluctuations.},
