    "abstract": "Ultrarelativistic heavy ion beams carry large electromagnetic and strong\nabsorptive fields, allowing exploration of a variety of physics. Two-photon,\nphoton-Pomeron, and double Pomeron interactions can probe a huge variety of\ncouplings and final states. RHIC will be the first heavy ion accelerator\nenergetic enough to produce hadronic final states via coherent couplings.\nVirtual photons from the nuclear EM fields can interact in two-photon\ninteractions, which can be exploited to study many particle spectroscopy and\nQCD topics. Because the photon flux scales as $Z^2$, Two-photon luminosities\nare large up to an energy of about \\gamma\\hbar c/R~ 3 GeV/c. Photon-Pomeron\ninteractions are sensitive to how different vector mesons, including the\n$J/\\psi$, interact with nuclear matter. $PP$ collisions rates are sensitive to\nthe range of the Pomeron. Signals can be separated from backgrounds by using\ncuts on final state isolation (rapidity gaps) and $p_\\perp$. We present Monte\nCarlo studies of different backgrounds, showing that representative signals can\nbe extracted with good rates and signal to noise ratios.",
