Anomalous Soft Photons associated with Hadron Production in String Fragmentation
Soft Photons Hadron Production String Fragmentation
2010/12/27
The bosonized QCD2+QED2 system for quarks with two flavors contains QCD2 and QED2 bound states, with an isoscalar photon at about 25 MeV and an isovector (I=1,I_3=0) photon at about 44 MeV. Consequen...

University of Oregon scientists have invented a method to change the color of single photons in a fiber optic cable. The laser-tweaked feat could be a quantum step forward for transferring and receivi...
Strong Limits on the Possible Decay of the Vacuum Energy into CDM or CMB Photons
the Vacuum Energy CDM CMB Photons
2010/10/18
We investigate models that suggest that the vacuum energy could decay into cold dark matter (CDM) or into a homogeneous distribution of thermalized cosmic microwave background (CMB) photons. We show t...
