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: QCD predicts a phase transition to quark gluon plasma. This plasma is now produced regularly in collisions of heavy nuclei at both RHIC and the LHC, and it exhibits remarkable properties. Its vanishingly small shear viscosity to entropy density …

Abstract: The CMS experiment has analyzed up to 140 fb-1 of pp collisions delivered by the LHC at 13 TeV. This data has allowed for improved precision in several aspects of Higgs-boson and electroweak physics and pushed the frontiers on …

ABSTRACT: Quantifying how terrestrial systems respond to climate change and other perturbations is challenging due to the complexity of associated processes that occur from bedrock-to-canopy and from genome to watershed scales. This presentation will describe the development of several new …
