Abstract: Many new results from a wide range of particle physics experiments and theoretical predictions were shown at the 54th Rencontres de Moriond. On the experimental side, they included updated ATLAS/CMS analyses (many using the full Run 2 dataset), probes …
ABSTRACT: What is common among a magnet, a halibut, a rack of laundry, your heart on the left of your body, and the Higgs boson? The concept of spontaneous symmetry breaking is ubiquitous among many natural phenomena. I'll describe …

Abstract: There have now been several generations of wide-field mm-wave surveys, with several ongoing and upcoming very ambitious projects. We have already learned a great deal about the early universe and put strong constraints on particle physics extensions to the …
ABSTRACT: The LHCb experiment has just discovered new narrow pentaquark states decaying to J/psi p, which shed more light into the nature of the J/psi p structures reported by LHCb in Lambda_b decays four years ago. We will describe these …
Abstract: “Recent measurements of observables involving the flavour changing neutral current transition b→sμ+μ− have shown an interesting pattern of tensions with respect to the predictions of the Standard Model (SM). However, the interpretation of these results is limited by our …
Precision measurements of the violation of charge-parity (CP) symmetry are crucial for testing the Standard Model and are sensitive probes for new physics contributions. While CP violation has been well-established by several different experiments in the decays of mesons containing …
ABSTRACT: The hypothesis of the existence of non-baryonic dark matter in our galactic halo is supported by all astrophysical observations performed from cosmological to local scales. The measurement of one clear experimental signal of this matter represents one of the …
ABSTRACT: Measurements of the Cosmic Microwave Background (CMB) temperature anisotropies and E-mode polarization have proven to be essential to our understanding of early universe cosmology by providing independent and strong evidence in favor of the Lambda-CDM cosmological model. However, there …
ABSTRACT: The CMS detector is being upgraded for the phase two of the LHC, where a dataset with much larger integrated luminosity will precisely measure the Higgs boson couplings and extend new phenomena searches to cover challenging scenarios with large …
Abstract: Measurements of the universe's present-day expansion rate, or the Hubble constant (H0), that use a Cepheid variable star calibration of Type Ia supernovae (SNe Ia) are in >4σ disagreement with values predicted by the standard, Lambda cold dark matter …
