Is a background worker in an async controller?

Question

Inside the asp.net mvc 2 controller, I have the following code:

using (BackgroundWorker worker = new BackgroundWorker())
                        {
                            worker.DoWork += new DoWorkEventHandler(blah);
                            worker.RunWorkerAsync(var);
                        }

My question is: is this async code meaning that it starts a new thread and the controller returns a view while blah is executed in parallel?

If not, how would you achieve these results?
