Abstract

Let F(k,q)\mathcal{F}(\textbf{k},\mathfrak{q}) be the set of primitive Hilbert modular forms of weight k\textbf{k} and prime level q\mathfrak{q}, with trivial central character. We study the one-level density of low-lying zeros of L(s,π)L(s,\pi) weighted by powers of central LL-values L(1/2,π)rL(1/2,\pi)^r, where π\pi runs through F(k,q)\mathcal{F}(\textbf{k},\mathfrak{q}). For r=1,2,3r=1,2,3, we show that the resulting distributions WrW_r match with predictions from Random Matrix Theory. For general r1r \geq 1, we also formulate a conjectural formula for WrW_r based on the ``recipe'' method.
