Working together with other UH Mānoa colleagues on the Belle experiment at the KEKB factory in Tsukuba, Japan, postdoctoral researcher Himansu Sahoo reported the first observation of a new type of rare “penguin decay” of the beauty quark and measured its matter-antimatter symmetry violation parameters. The results will be published in the October 2011 issue of Physical Review D Rapid Communications. Sahoo is the first author of this paper, which was the basis for his Phd dissertation at UH Mānoa.
In beauty quark and other radioactive decays observed to date, the interactions responsible for the decay violate mirror symmetry and are left-handed. Sahoo’s paper establishes a new method for searching for right-handed currents from physics beyond the Standard Model that will be used in future very high luminosity experiments.
Sahoo is a recent physics and astronomy department Phd graduate.
