SUMMARY:National Superconducting Cyclotron Laboratory Seminar
DESCRIPTION:
 Hans-Werner Hammer from TU Darmstadt Institute 
 of Nuclear Physics will be speaking.\n
 \n
 The 
 presentation is titled "Theory Center Structure 
 and lifetime of the hypertriton."\n
 \n
 We calculate 
 the structure of the hypertriton in pionless 
 effective field theory and find a pronounced 
 Lambda-deuteron cluster structure. This 
 motivates our investigation of the hypertriton 
 lifetime as a function of the Lambda separation 
 energy in an effective field theory with 
 Lambda and deuteron degrees of freedom. We 
 also consider the impact of new measurements 
 of the weak decay parameter of the Lambda. 
 While the sensitivity of the total width to B_Lambda 
 is small, the partial widths for decays 
 into individual final states and the experimentally 
 measured ratio R=Gamma_3He/(Gamma_3He+Gamma_pd) 
 show a strong dependence. We comment 
 on recent measurements of hypertriton properties 
 in heavy ion collisions.\n\n
