This paper considers composition operators on Zen spaces (a class of weightedBergman spaces of the right half-plane related to weighted function spaces onthe positive half-line by means of the Laplace transform). Generalizations aregiven to work of Kucik on norms and essential norms, to work of Schroderus on(essential) spectra, and to work by Arvanitidis and the authors on semigroupsof composition operators. The results are illustrated by consideration of theHardy--Bergman space; that is, the intersection of the Hardy and BergmanHilbert spaces on the half-plane.
