Do it with a LEXER rule instead of a parser rule.
AUTHOR : LTR LTR LTR LTR LTR LTR LTR LTR LTR LTR
;
If you still need to do something in a parser rule, do it as
author : AUTHOR
{ ... }
;

Having a lexer rule that matches any single character is going to get
you into trouble later on if you are not careful. The whole point of
lexing to the convert single characters into TOKENs which can then be
parsed by the parser.
