The LHCb collaboration has measured a difference in mass between two particles of 0.00000000000000000000000000000000000001 grams – or, in scientific notation, 10-38 g. The result, reported in a paper ...
Low Mass Gluino within the Sparticle Landscape, Implications for Dark Matter, and Early Discovery Prospects at LHC-7
Low Mass Gluino Implications for Dark Matter Early Discovery Prospects
2011/1/5
We analyze supergravity models that predict a low mass gluino within the landscape of sparticle mass hierarchies. The analysis includes a broad class of models that arise in minimal and in non-minimal...
Head-on collisions of unequal mass black holes in D=5 dimensions
Head-on collisions of unequal mass black holes D=5 dimensions
2010/12/20
We study head-on collisions of unequal mass black hole binaries in D = 5 spacetime dimensions,
with mass ratios between 1:1 and 1:4. Information about gravitational radiation is extracted by
using t...
Developments in accelerator mass spectrometry (AMS) method for 182Hf
182Hf accelerator mass spectrometry (AMS) HfF4 injector solid-phase reaction
2009/8/14
The present detection limit for 182Hf at CIAE HI-13 AMS systems could not satisfy various applications (e. g. detection of a nearby supernovae signal). Therefore, techniques were developed in this wor...
