Abstract (SISSA): We present results on light weakly interacting massive particle (WIMP) searches with annual modulation (AM) analysis on data from a 1-kg mass p-type point-contact germanium detector of the CDEX-1B experiment at the China Jinping Underground Laboratory. The 90% C.L. allowed regions implied by the DAMA/LIBRA and CoGeNT AM-based analysis are excluded at >99.99% and >98% C.L., respectively. These results correspond to the best sensitivities at WIMP masses below 6 GeV among WIMP AM measurements.
