#CMSPaper 1299 measures the momentum of Higgs bosons. As kinematic properties of particles are affected by higher-order quantum effects, this is a very good way to measure the standard model and check if the behavior agrees. But even in the tau-tau final state we still don't have so many Higgs bosons, so still very large uncertainties https://arxiv.org/abs/2403.20201
Are there undiscovered heavy particles decaying to #Higgsbosons? #CMSPaper 1297 is an overview paper with all searches for Higgs boson resonances (as the Higgs boson can decay in many ways, there are also many signatures to examine). Such resonances would exist in scenarios with extra dimensions, more Higgs bosons, more W or Z bosons, and even if gravitons would exist and made at the LHC! We did not see any, so give constraints on what is still consistent with the data https://arxiv.org/abs/2403.16926
The frequency of simultaneous production of two Higgs bosons would allow us to directly measure the (Brout-Englert-)Higgs field at the LHC. We don't see it yet, and this specific #CMSPaper 1293 looks for it in the very common bbWW signature: https://arxiv.org/abs/2403.09430
There are a lot of composite particles containing b quarks, and their decay is interesting (the LHC even has a dedicated experiment to study them, @LHCbExperiment). But are there undiscovered particles (for example, extra undiscovered neutrinos) hiding in those B meson decays? #CMSPaper 1291 checks, and did not see any. https://arxiv.org/abs/2403.04584
The top quark is super heavy, and no one knows why. #CMSPaper 1289 is an overview of top quark measurements by the CMS experiment. It is also possible to measure that mass in many ways as a consistency check (that helps us understand it if those methods are all very different) https://arxiv.org/abs/2403.01313
