The Higgs boson can decay to many different particles from the standard model. But... is the Higgs boson also decaying to undiscovered particles? This #CMSPaper looks for extra (light) bosons that would create the Higgs boson to four electron signature arxiv.org/abs/2511.19563

This #CMSPaper looks for production of photons in these boson collisions, meaning the LHC is a W boson collider, which is the first time this has ever been seen! It measures properties of the photons produced and compares them to the standard model predictions arxiv.org/abs/2512.00502

This #CMSPaper measures the simultaneous production of Z bosons and photons. That way their interactions can be measured and can be compared to predictions by the standard model arxiv.org/abs/2512.08582

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

Are there undiscovered charged heavy Higgs bosons? If they are heavier than the top quark, they would decay into a top quark + b quark signature. This #CMSPaper looks for these, and also compares them in dedicated theory frameworks that include neutral heavy Higgs bosons arxiv.org/abs/2512.24471

One of the classical ways to look for undiscovered particles at the LHC is to look for unexpected resonances in the jets coming from quarks and gluons. This #CMSPaper compares the cutting edge of #machinelearnining #ai methods to see how well they do for top quark resonances arxiv.org/abs/2512.20395

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! arxiv.org/abs/2601.05362

This #CMSPaper measures the production of a photon and a Z boson (so the neutral quantum particles of electromagnetism and the weak force). This paper specifically looks if there are any signs that explain why our universe contains more matter than antimatter, and it's the world most sensitive result for that signature https://arxiv.org/abs/2601.14102

Non-standard model signatures like long-lived particles can be very difficult to spot. And as the LHC throws away over 99% of it's (supposedly uninteresting) background data, it is super important to make sure we keep those long-lived particles, and this #CMSPaper summarises all we do to make that happen https://arxiv.org/abs/2601.17544 It has a large contribution from our group at DESY and includes work from doctoral students I supervised 👩‍🏫 🎓️

If there are supersymmetry versions of tau leptons (creatively called "stau" or scalar-tau), they could create signatures where 'normal' taus appear in the middle of the CMS detector. This #CMSPaper looks for such displaced taus, and describes the #machinelearning needed to spot them. It is a result from our group at DESY by the way :) https://arxiv.org/abs/2601.17576
