Abstract
Inspir\'es par un argument de C. Voisin, nous montrons l'existence d'hypersurfaces quartiques lisses dans qui ne sont pas stablement rationnelles, plus pr\'ecis\'ement dont le groupe de Chow de degr\'e z\'ero n'est pas universellement \'egal \`a . --- There are (many) smooth quartic hypersurfaces in which are not stably rational. More precisely, their degree zero Chow group is not universally equal to . The proof uses a variation of a specialisation method due to C. Voisin.
