Hadronic form factors and the secondary production cross section: an update
F. Carvalho, F. O. Durães, F. S. Navarra +1
Improving previous calculations, we compute the cross section using the most complete effective lagrangians available. The new crucial ingredients are the…
Running couplings for the simultaneous decoupling of heavy quarks
Steven D. Bass, R. J. Crewther, F. M. Steffens +1
Scale-invariant running couplings are constructed for several quarks being decoupled together, without reference to intermediate thresholds. Large-momentum scales can also be inclu…
Search for Planetary Candidates within the OGLE Stars
Adriana V. R. Silva, Patricia C. Cruz
We propose a method to distinguish between planetary and stellar companions to stars which present a periodic decrease in brightness, interpreted as a transit. Light curves from a…
Kaon Condensation and Lambda-Nucleon Loop in the Relativistic Mean-Field Approach
Tomoyuki Maruyama, Takumi Muto, Toshitaka Tatsumi +2
The possibility of kaon condensation in high-density symmetric nuclear matter is investigated including both s- and p-wave kaon-baryon interactions within the relativistic mean-fie…
