Query: Sharp upper bounds for fractional moments of the Riemann zeta function   We establish sharp upper bounds for the $2k$th moment of the Riemann zeta
function on the critical line, for all real $0 \leqslant k \leqslant 2$.
  This improves on earlier work of Ramachandra, Heath-Brown and
Bettin-Chandee-Radziwi\l\l
