WebJun 27, 2024 · Hyperon–nucleon interaction within chiral effective field theory revisited. The $$\varLambda N$$ Λ N and $$\varSigma N$$ Σ N interactions are considered at next-to-leading order in SU (3) chiral effective field theory. Different options for the low-energy constants that determine the strength of the contact interactions are explored. WebBolm’s team are convinced that the TLA experiments show that solid–solid interactions are the main factor influencing the sublimation properties of materials. ‘While in this case two enantiomers of the same compound recognised each other in the solid state, such self-finding processes can also involve two different chiral molecules ...
