What we Learned from A(e,e)X Reactions
20
neutron proton 6p and 6n rate calculate the expected proton rate
21
92% of the time two-nucleon high density fluctuations are ptoron and neutron 4% of the time proton-proton or neutron-neutron Piasetzky, Sargsian, Strikman, Frankfurt, Watson PRL 2006 Important Implication for the structure of the neutron stars

In the Lab
27
Chemical Potential and Quantum Field Classical Thermodynamics for Open Systems Added energy due to Ni matter introduced to the system Diffusive Equilibrium
28
Particles in the Cold Dense Matter Everything may change when kinetic energy of NN system exceeds 300 MeV The system becomes effectively open Particles which leave the star do not contribute in
29
Kaon Condensation Interaction is attractivekaon energy decreases with density Strangeness Enhancement
