Nuclear structure and reactions from chiral two- and three-nucleon forces*

In recent years, significant progress has been made in ab initionuclear structure and reaction calculations based on input from QCD employing Hamiltonians constructed within chiral effective field theory. One of the recently developed approaches is the No-Core Shell Model with Continuum (NCSMC) [1,2], capable of describing both bound and scattering states in light nuclei simultaneously. I will present latest NCSMC calculations of weakly bound states and resonances of exotic halo nuclei such as ⁶He and ¹¹Be and discuss strong E1 transitions and photo-dissociation of ¹¹Be. I will also present our results for unbound nuclei such as ⁷He, ⁹He and ¹¹N and highlight the role of chiral NN and 3N interactions. Further, I will present our calculations of the ¹¹C(p,p) scattering and the astrophysical relevant ¹¹C(p,γ)¹²N radiative capture. Finally, I will discuss polarization effects in the ³H(d,n)⁴He fusion.
