    Initializing BSQ with Open-Source ICCING

    Patrick Carzon🇺🇸 · Mauricio Martinez🇺🇸 · Matthew D. Sievert🇺🇸 · Douglas E. Wertepny🇮🇱 · Jacquelyn Noronha-Hostler🇺🇸

    While it is well known that there is a significant amount of conserved charges in the initial state of nuclear collisions, the production of these due to gluon splitting has yet to be thoroughly investigated. The ICCING (Initial Conserved Charges in Nuclear Geometry) algorithm reconstructs these quark distributions, providing conserved strange, baryon, and electric charges, by sampling a given model for the splitting function over the initial energy density, which is valid at top collider energies, even when . The ICCING algorithm includes fluctuations in the gluon longitudinal momenta, a structure that supports the implementation of dynamical processes, and the c++ version is now open-source. A full analysis of parameter choices on the model has been done to quantify the effect these have on the underlying physics. We find there is a sustained difference across the different charges that indicates sensitivity to hot spot geometry.

    Investigating the muon catalyzed fusion in muonic lithium hydride

    Qian Wu · Xurong Chen

    In this work, we consider the muonic LiH as a new stage of the catalyzed fusion. We calculate the bound states of the muonic LiH and LiH and their wave functions based on the three and four body approximation. In order to solve the Schrdinger equation, we apply the Gaussian expansion method which gives us both the eigen energies and the wave functions. The existences of the bound states in muonic LiH and LiH are confirmed. We find the dynamical behaviors between the Li and proton in muonic LiH and LiH are similar as the ones in dt and dt, respectively. The sticking probability in the muonic LiH after the nuclear fusion is studied. The calculated sticking probability of being captured to the ground state of He is 5 times smaller than the one in dt.

    Influence of heavy resonances in SMASH

    J. Salinas San Martin🇺🇸 · J. Noronha-Hostler🇺🇸 · H. Elfner🇩🇪 · J. Hammelmann🇩🇪 · R. Hirayama🇩🇪

    Recent lattice QCD results, comparing to a hadron resonance gas model, have shown the need for hundreds of particles in hadronic models. These extra particles influence both the equation of state and hadronic interactions within hadron transport models. Here, we introduce the PDG21+ particle list, which contains the most up-to-date database of particles and their properties. We then convert all particles decays into 2 body decays so that they are compatible with SMASH in order to produce a more consistent description of a heavy-ion collision.

    CME -- Experimental Results and Interpretation

    Fuqiang Wang🇺🇸

    The experimental status is reviewed on the search for the chiral magnetic effect (CME) in relativistic heavy-ion collisions. Emphasis is put on background contributions to the CME-sensitive charge correlation measurements and their effects on data interpretation.
