New ideas are rare in particle physics these days. Solutions to the naturalness problem of the Higgs mass are true collector's items. Fo...

The ATLAS diboson resonance search showing a 3.4 sigma excess near 2 TeV has stirred some interest. This is understandable: 3 sigma does no...

This weekend's plot shows the region in the stop mass and mixing space of the MSSM that reproduces the measured Higgs boson mass of 125 ...

Last night, for the first time, the LHC  collided particles at the center-of-mass energy of 13 TeV. Routine collisions should follow early i...

This weekend plot completes my last week's post : It shows the phase diagram for models of natural electroweak symmetry breaking. Th...

Last week Symmetry Breaking ran the article entitled " Natural SUSY's last stand ". That title is a bit misleading as it mak...

Here is a late weekend plot with new limits on the dark photon parameter space: The dark photon is a hypothetical massive spin-1 boson m...
