Ab initio description of p-shell hypernuclei.
We present the first ab initio calculations for p-shell single-Λ hypernuclei. For the solution of the many-baryon problem, we develop two variants of the no-core shell model with explicit Λ and Σ(+),Σ(0),Σ(-) hyperons including Λ-Σ conversion, optionally supplemented by a similarity renormalization group transformation to accelerate model-space convergence. In addition to state-of-the-art chira...
متن کاملImportance Truncated No-Core Shell Model
One of the most universal tools for the ab initio solution of the nuclear many-body problem is the No-Core Shell Model (NCSM). It is widely used for the description of ground states and low-lying excited states of nuclei throughout the p-shell [1]. Apart from energies, detailed spectroscopic information and form-factors can be extracted from the resulting many-body eigenstates. The limitation o...
متن کاملShell-Model Description of Λ Hypernuclei
Empirical data on the spectra of light hypernuclei, especially the data from recent γ-ray experiments, is used to constrain the parameters which govern the p N s Λ and p N p Λ two-body matrix elements that enter into shell-model calculations.
متن کاملAb initio no-core shell model calculations for light nuclei
— An overview of the ab initio no-core shell model is presented. Recent results for light nuclei obtained with the chiral two-nucleon and three-nucleon interactions are highlighted. Cross section calculations of capture reactions important for astrophysics are discussed. The extension of the ab initio no-core shell model to the description of nuclear reactions by the resonating group method tec...
متن کاملRecent developments in no-core shell-model calculations
We present an overview of recent results and developments of the no-core shell model (NCSM), an ab initio approach to the nuclear many-body problem for light nuclei. In this approach, we start from realistic two-nucleon or twoplus threenucleon interactions. Many-body calculations are performed using a finite harmonicoscillator (HO) basis. To facilitate convergence for realistic inter-nucleon in...
