   Strangeness Physics with CLAS at JLab

   Volker D. Burkert🇺🇸

   A brief overview of strangeness physics with the CLAS detector at JLab is given, mainly covering the domain of nucleon resonances. Several excited states predicted by the symmetric constituent quark model may have significant couplings to the K-Lambda or K-Sigma channels. I will discuss data that are relevant in the search for such states in the strangeness channel, and give an outlook on the future prospects of the N* program at JLab with electromagnetic probes.

   Deeply Virtual Compton Scattering with Positron Beams at Jefferson Lab

   Volker D. Burkert🇺🇸

   A brief discussion of the DVCS program at the Jefferson Lab 12 GeV energy upgrade is given. Emphasis is on what can be learned from using both polarized electron and polarized positron beams in conjunction with polarized nucleon targets.

   The STAR W Spin Physics Program with $\sqrt{(}s)$ = 500 GeV Polarized pp Collisions at RHIC

   W.W. Jacobs (for the STAR Collaboration)🇺🇸

   Production of W bosons in longitudinally polarized pp collisions provides an excellent tool to probe the flavor-dependence of sea quark polarizations in the polarized proton. Current status and future plans for the W physics program with the STAR detector at RHIC are presented along with remarks concerning our knowledge of the nature and origin of the partonic sea.

   Evidence of double magicity of N=Z nuclei near the rp-process path

   M.M. Sharma🇰🇼 · J.K. Sharma🇮🇳

   N=Z nuclei above Ni are understood to be waiting-point nuclei in the rp-process nucleosynthesis. Investigating the experimental isotope shifts in Kr isotopes near the proton drip-line, we have discovered that N=Z rp-process nuclei ${}^{68}$Se, ${}^{72}$Kr, ${}^{76}$Sr and ${}^{80}$Zr exhibit a significant shell gap both at the proton and neutron numbers in the deformed space with the consequence that pairing correlations for protons and neutrons vanish, thus lending a double-magic character to these nuclei. A significant number of nuclei in this region are also shown to exhibit neutron magicity at N = 34, 36, 38, and 40 in the deformed space.
