Gravitons exist in all sorts of grand unification physics theories. This #CMSPaper looks for them in the photon+missing energy signature, which is also a good signature to check for #darkmatter by the way. It looks in the 2016 through 2018 CMS data, and is a #nullresult arxiv.org/abs/2511.17310

Hypothetical supersymmetry particles linked to Higgs bosons (called Higgsinos) are linked to #darkmatter. This #CMSPaper looks for the low-momentum + missing-energy signature. There is some deviation (2.2 sigma) in this analysis, so we will look at it again with more data! arxiv.org/abs/2511.16394

Are there undiscovered particles that decay to a Higgs boson and a photon? Or a Z boson and a photon? (at high momentum it's difficult to see the difference between a Higgs boson and a Z boson) This #CMSPaper looks for a very massive resonance from such a particle. arxiv.org/abs/2511.14583

This #CMSPaper measures the Higgs boson when it has high momentum. This is important to test the standard model because deviations are more likely to show up there. But we don't really see the Higgs boson there yet. This result will help when combined with other results tho! https://arxiv.org/abs/2601.05362

This #CMSPaper measures the Higgs boson when it has high momentum. This is important to test the standard model because deviations are more likely to show up there, and it needs a dedicated paper because the way you identify the Higgs boson is different and requires novel analysis techniques (e.g. look for structure inside jets to see a Higgs boson) . But we don't really see the Higgs boson there yet. This result will help when combined with other Higgs-y results tho! https://arxiv.org/abs/2601.05362

Are there extra Z-boson like undiscovered particles made at higher mass? Or did we miss them because they can only see them when they're made together with quarks? This #CMSPaper scans the dimuon spectrum - it is a #nullresult (no extra Z' bosons spotted!) arxiv.org/abs/2511.11853

I heard last week that the physics teacher of the daughter of one of my colleagues told the daughter that girls who do their nails don’t do physics. Sigh.

So, here are the nails of an internationally leading particle physics professor. My nails.

Don’t believe the gatekeepers! #womeninSTEM
