Application of chiral 2- and 3-baryon interactions to light hypernuclei

Hypernuclei provide important information to constrain the hyperon-nucleon (YN) and three- baryon (YNN) interactions. In this presentation, I discuss recent results obtained using chiral YN and YNN interactions for light hypernuclei. This includes studying the charge-symmetry breaking of YN interactions and its impact on 𝑝-shell Λ-separation energies. After estimating the size of YNN forces using estimates of contributions of higher orders of the chiral expansion, I also show some first results of the application of chiral YNN forces.

Abstract

Hypernuclei provide important information to constrain the hyperon-nucleon (YN) and three- baryon (YNN) interactions. In this presentation, I discuss recent results obtained using chiral YN and YNN interactions for light hypernuclei. This includes studying the charge-symmetry breaking of YN interactions and its impact on 𝑝-shell Λ-separation energies. After estimating the size of YNN forces using estimates of contributions of higher orders of the chiral expansion, I also show some first results of the application of chiral YNN forces.
