Query: Affine Hall-Littlewood functions for $A_1^{(1)}$ and some constant term
  identities of Cherednik-Macdonald-Mehta type   We study $t$-analogs of string functions for integrable highest weight
representations of the affine Kac-Moody algebra $A_1^{(1)}$. We obtain closed
form formulas for certain $t$-string functions of levels 2 and 4. As
corollaries, we obtain explicit identities for the corresponding affine
Hall-Littlewood functions, as well as higher-level generalizations of
Cherednik's Macdonald and Macdonald-Mehta constant term identities.
