Dear Colleages,

Please join us for our next S at INT seminar on *Tuesday, March 14nd at 10:30
AM Pacific Time* by James Lattimer – Stony Brook University

*Title:*

“Tight Symmetry Energy Parameter Constraints from Neutron Skin Measurements*”
*



*Abstract:*
Inferences of nuclear symmetry energy parameters from recent
parity-violating neutron skin measurements of the neutron-rich nuclei Ca-48
and Pb-208 appear to be in tension with each other and values obtained from
fitting either nuclear masses or neutron matter theory. By themselves, PREX
I+II measurements of Pb-208 and CREX measurements of Ca-48 suggest L≃110±36
MeV and L≃23±27 MeV, respectively, to 68% confidence. However, jointly
satisfying both at 90% confidence implies L≃51±11MeV, nearly exactly the
range suggested by nuclear mass fitting or neutron matter theory. This
small inferred parameter range is also consistent with nuclear dipole
polarizability measurements and X-ray and gravitational wave observations
of neutron stars.



This event will take place in the INT seminar room (C-421). All interested
graduate students and faculty are invited to attend.



Participants are also welcome to join via Zoom.
