Abstract

Let π\pi be a Hecke-Maass cusp form for SL(3,Z)SL(3,\mathbb{Z}) and χ=χ1χ2\chi=\chi_1\chi_2 a Dirichlet character with χi\chi_i primitive modulo MiM_i. Suppose that M1M_1, M2M_2 are primes such that max{(Mt)1/3+2δ/3,M2/5t9/20,M1/2+2δt3/4+2δ}(Mt)ε<M1<min{(Mt)2/5,(Mt)1/28δ}(Mt)ε\max\{(M|t|)^{1/3+2\delta/3},M^{2/5}|t|^{-9/20}, M^{1/2+2\delta}|t|^{-3/4+2\delta}\}(M|t|)^{\varepsilon}<M_1< \min\{ (M|t|)^{2/5},(M|t|)^{1/2-8\delta}\}(M|t|)^{-\varepsilon} for any ε>0\varepsilon>0, where M=M1M2M=M_1M_2, t1|t|\geq 1 and 0<δ<1/520<\delta< 1/52. Then we have L(12+it,πχ)π,ε(Mt)3/4δ+ε. L\left(\frac{1}{2}+it,\pi\otimes \chi\right)\ll_{\pi,\varepsilon} (M|t|)^{3/4-\delta+\varepsilon}.
