Bibliography of recent (as of May 2020) small system jet results at RHIC:

PHENIX measurements:

1. Preliminary R_{p/d/3He+Au} for pi-0 in proceedings from ICNFP 2017 at  linked talk, "Recent PHENIX results on high-pT light hadron production".
    
2. Semi-inclusive particle production (delta-phi) relative to pi-0 in p+Au, p+Ag, and correlation yields in d+Au at QM2019, "Probing Modification of the Initial State in Small Systems via Jets Detected in PHENIX".
    
3. There are several v2 and v3 measurements of p/d/3He+Au from Phenix. A recent is March 2019 in Nature, "Creation of quark–gluon plasma droplets with three distinct geometries".
    
4. Of course, the 2015 R_{p+Au} jet paper: "Centrality-Dependent Modification of Jet-Production Rates in Deuteron-Gold Collisions at $\sqrt{s_\mathrm{NN}}$ =  200 GeV".

STAR:

1. QM2019, BEMC+jet in p+Au, "Correlation measurements of charged particles and jets at mid-rapidity with event activity at backward-rapidity in \sqrt{s_\mathrm{NN}} = 200 GeV p+Au collisions at STAR".
