  1. 39. In-medium generator coordinate method for nuclear collective excitations and double-beta decays

  2. 2. Investigation of the Coulomb interaction in finite nuclei
    Kenta Hagihara (University of Tsukuba)
    4/13/26, 11:00 AM

    The ground-state properties of nuclei can be described within the liquid-drop model, where nuclear stability against deformation is governed by the competition between the surface energy and the Coulomb energy. The Coulomb interaction also plays an essential role in spontaneous fission. Motivated by these considerations, we focus on nuclear deformation and Coulomb effects in finite nuclei. To...

  4. 37. Benchmarking nuclear matrix elements of 0νββ decay with high-energy nuclear collisions
    Xin Zhang
    4/13/26, 2:30 PM

    Reducing uncertainties in the nuclear matrix element (NME) remains a critical challenge in designing and interpreting experiments aimed at discovering neutrinoless double beta (0νββ) decay. Here, we identify a class of observables, distinct from those employed in low-energy nuclear structure applications, that are strongly correlated with the NME: momentum correlations among hadrons produced...

  5. 6. From heavy-ion to small systems and forward region: Effects from early stage dynamics
    Shujun Zhao (Sophia university)
    4/14/26, 10:00 AM
  6. 10. Tip–Tip Collisions of Deformed Nuclei as a Probe of the High-Density Equation of State
    Chiho Nonaka (Hiroshima University / Nagoya University)
    4/14/26, 11:00 AM

    We explore the equation of state (EOS) of dense nuclear matter using central collisions of deformed nuclei, focusing on tip–tip collisions. In collisions of strongly deformed nuclei such as Er, geometric asymmetry remains even in central events, resulting in a finite elliptic flow. Because flow observables are sensitive to the EOS, selecting specific collision geometries can provide...

  7. 41. Shape of 12C
    masaaki Kimura (RIKEN)
    4/14/26, 2:00 PM
  8. 13. RHC opportunities for clarifying nuclear shapes
    Takaharu Otsuka
    4/14/26, 2:30 PM

    I will first discuss that virtually all deformed are triaxial, but this fundamental feature needs to be confrimed by many independent experiments. The RHC is one of them, and should play an important role. I will also discuss whether the RHC is a fundamentally valid approach in terms of time evolution of strongly deformed nuclei. (If you need a longer one, please let me know.)

  14. 3. Towards a microscopic description of 12C+12C fusion
    Pierre Descouvemont
    4/16/26, 2:00 PM

    I present a fully microscopic description of the 12C+12C fusion reaction at stellar energies. Utilizing the multichannel Resonating Group Method (RGM), my model explicitly includes 12C+12C and alpha+20Ne reaction channels (with excited states). Results for 12C+12C elastic scattering show excellent agreement with experimental data, significantly improving the single-channel approximations....

  15. 4. A microscopic discription of carbon fusion reactions at nuclear astrophysical energy
    Kosei Nagao
    4/16/26, 2:30 PM

    The 12C + 12C fusion reaction plays a key role in several astrophysical explosive phenomena. However, the cross section for the 12C + 12C fusion reaction at the relevant energy region is difficult to determine because of both experimmental limitations and strong resonant structures. We develop a reaction model that explicitly treat the C + C channel and Mg channel. The model reproduces the...

  16. 9. Recent progress in nuclear lattice effective field theory
    Bingnan Lu
    4/17/26, 10:00 AM

    I will give a brief review of several recent progress in the lattice Monte Carlo algorithms applied in nuclear lattice effective field theory (NLEFT), including the sign-problem-free action for heavy nuclei, second-order perturbative calculation with N$^3$LO chiral forces, renormalization group invariance of light nuclei in NLEFT, etc.

  17. 17. Effect of dynamical flow responses on NeNe and OO flow ratios
    Clemens Werthmann (Ghent University)
    4/17/26, 11:00 AM

    In contrast to heavy ions, in ultra-central light ion collisions flow response coefficients can vary significantly. This has to be taken into account when inferring statements about the shape of the nuclei from final state flow, which can become even more difficult when the applicability of hydrodynamics is questionable. I will present and discuss results for flow responses in NeNe and OO...

  18. 18. A New ”Skin Thickness” in High-Spin Isomers as a Probe for Equation of State of Spin-polarized matter
    Toi Tachibana
    4/17/26, 11:30 AM

    In T. Tachibana et al., Phys. Rev. C 112 (2025) 065806, the equation of state of spin-polarized nuclear matter was studied and the spin slope parameter of the corresponding spin-symmetry energy was discussed, which plays an important role in characterizing spin-dependent properties of nuclear systems. To explore a possible experimental probe for constraining the spin slope parameter, we...

  20. 20. On the Quantum Nature of Nuclear Deformations in Heavy-ion Collisions
    Weiyao Ke (Central China Normal University)
    4/20/26, 11:30 AM

    High-energy collisions are a promising tool to study nuclear deformation, but they pose a conceptual challenge: nuclei are quantum objects whose ground state is a superposition of intrinsic deformed configurations at orientations. How does this quantum nature affect the semi-classical geometry of the Quark-Gluon Plasma fireball? I will argue that the collision does not project the nucleus onto...

  21. 21. The neutron skin thickness from low-energy experiments
    Xavier Roca Maza
    4/20/26, 2:30 PM

    In this talk I will discuss different theoretical analysis of some selected experimental data on low-energy nuclear observables --such as the dipole polarizability [1-3], the parity violating asymmetry [2-5] or the excitation energy of the Isobaric Analog State [6]-- that give access to the neutron skin thickness in medium and heavy nuclei. These measurements are complementary to the recent...

    Reyes Alemany Fernandez (CERN)
    4/21/26, 11:30 AM

    In recent years, interest in conducting experiments with lighter ions than lead at the CERN Accelerator Complex has grown significantly within the ion-physics community. Collisions such as Xe‑Xe, O‑O, Ne‑Ne, and p‑O have already been delivered to the LHC. Comparisons across these systems offer a unique opportunity to probe nuclear‑geometry‑driven hydrodynamic flow in light‑ion systems at LHC...

  27. 27. Neutron Skin from Conserved Charge Measurements at Collider Experiments
    Bjoern Schenke
    4/22/26, 10:00 AM

    We propose a novel method for measuring the neutron skin of heavy nuclei using collider experiments. Specifically, we demonstrate that the neutron skin thickness of the lead nucleus can be extracted in p+Pb collisions by analyzing a double ratio: The ratio of net electric charge to net baryon number measured near the lead-going rapidity, taken for high-multiplicity events and divided by the...

    We report the current status of the simulation of the Xe+Xe collisions based on an integrated dynamical model with stochastic hydrodynamics and JAM2 and discuss the relevant observables. We also present the explicit expression of the unbiased estimator for the detector efficiency correction of an arbitrary observable, which unifies existing correction formulae for various variables, including...

    Naoya Ito
    4/24/26, 3:30 PM

    In high-energy nuclear collisions, numerous phenomenological analyses have been conducted regarding the Quark-Gluon Plasma (QGP) as it reaches local thermal equilibrium. In these studies, it is crucial to understand the extent to which the QGP is actually generated as a transient state of the collision. While the QGP component is dominant in large collision systems such as Pb+Pb, it remains...
