Seamers Stuart Broad and Chris Woakes both miss out on selection for the 15-man squad, but Steven Finn is included despite his recent struggles with injury.
As expected England overlooked Kevin Pietersen, despite his excellent recent form in South Africa's Ram Slam competition and Australia's Big Bash League.
The Super 10 stage of the tournament starts on March 15, with England playing their Group One opener the following day against the West Indies.
Also in their group are Sri Lanka, South Africa and one qualifier from Zimbabwe, Afghanistan, Scotland and Hong Kong.

England coach Trevor Bayliss admitted that he does not know too much about the latest member of his squad.
"I haven't actually seen him play a game. He came to a practice when we were out in the UAE, and he was there with the Lions," Bayliss said.
But the Australian added: "I went to one or two of their (England Lions) practices and saw him in the nets.
"He can bat as well, and he's a good fielder apparently."
Australian Bayliss said that he was considering keeping Finn on the current tour of South Africa, but decided to give him time to rest ahead of the tournamant in India.
But Bayliss was quick to reiterate that a return for
Pietersen is just not going to happen.
"He wasn't even discussed in the selection meeting," he said.
"Everyone is very happy with the young team we've got ... we've played very well in Twenty20 cricket over the last six months.
Chris Woakes has been a regular in recent sides for all formats of the game, but the bowling all-rounder misses out as England look to a three-man spin attack of Dawson, Moeen Ali and Adil Rashid to lead the way on the sub-continent.
Former Twenty20 captain Broad was recently recalled to the one-day international squad for the ongoing series in South Africa, but he is yet to play a match in that series and will not return to the international version of the shortest form of the game next month.
Full England squad for World Twenty20:
Eoin Morgan (capt), Alex Hales, Jason Roy, Joe Root, James Vince, Jos Buttler, Sam Billings, Ben Stokes, Moeen Ali, Liam Dawson, David Willey, Chris Jordan, Adil Rashid, Reece Topley, Steven Finn.
