 Dyson's Laurent polynomial.When all the values "a""i" are equal to β/2, the constant term in Dyson's conjecture is the value of Dyson's integral

Dyson's integral is a special case of Selberg's integral after a change of variable and has value

which gives another proof of Dyson's conjecture in this special case.found a q-analog of Dyson's conjecture, stating that the constant term of 
is 
Here ("a";"q")"n" is the q-Pochhammer symbol.
