We calculate the shift in the masses and decay constants of 
and 
mesons in hot and dense asymmetric strange hadronic matter using QCD sum rules and chiral SU(3) model. In-medium strange quark condensates 
, and gluon condensates 
, to be used in the QCD sum rules for pseudoscalar and mesons, are calculated using a chiral SU(3) model. As an application of our present work, we calculate the in-medium decay widths of the excited (
) states 
and 
decaying to (
) mesons. The medium effects in their decay widths are incorporated through the mass modification of the and 
mesons. The results of the present investigation may be helpful in understanding the possible outcomes of the future experiments like CBM and PANDA under the FAIR facility.
