FINITE HOCHSCHILD COHOMOLOGY WITHOUT FINITE GLOBAL DIMENSION

Dieter Happel asked the following question: If the $n$-th Hochschild cohomology group of a finite dimensional algebra $\Gamma$ over a field vanishes for all sufficiently large $n$, is the global dimension of $\Gamma$ finite? We give a negative answer to this question.
