Hi Thierry,
TTree::CloneTree creates a new TTree object. This new object is
automatically
added to the list of objects associated to your current directory/file.
This object will be automatically deleted when you close this
directory/file.
You can delete this object in your class destructor if you do not need
this object before you close the file.
use
gDirectory->ls();
to see the list of objects in your current directory.

use
gObjectTable->Print();
to see the total number of objects per class
