Abstract = {{The charge and spin correlations in La1.875Ba0.125CuO4 (LBCO 1/8) are
   studied using Cu L-3 edge resonant inelastic x-ray scattering (RIXS).
   The static charge order (CO) is observed at a wave vector of (0.24,0)
   and its charge nature confirmed by measuring the dependence of this peak
   on the incident x-ray polarization. The damped spin excitation or
   ``paramagnon{''} in LBCO 1/8 is then measured as it disperses through
   the CO wave vector. Within the experimental uncertainty no changes are
   observed in the paramagnon at that wave vector and the paramagnon seems
   to be similar to that measured in other cuprates, which have no static
   CO. Given that the stripe correlation modulates both the charge and spin
   degrees of freedom, it is likely that subtle changes do occur in the
   paramagnon due to CO. Consequently, we propose that future RIXS
   measurements, realized with higher-energy resolution and sensitivity,
   should be performed to test for these effects.}},
