Introduction to Effective Field theory in Particle Physics

Mini-Course (24-28 June 2024, CINVESTAV, Mexico)

Dr. Benjamin Grinstein,

University of California, San Diego, USA

This five lesson minicourse introduces the student to the technology of Effective Field Theory (EFT). Going well beyond a presentation of the conceptual basis for EFTs, we describe how computations are performed and in passing review aspects of dimensional regularization and of the renormalization group. Examples are drawn from applications of EFT to SU(5) grand-unification and to the standard model of electroweak interactions and Quantum Chromodynamics. One last lesson will be devoted to Heavy Quark Effective Theory, as a prototype to EFTs that describe restricted kinematic domains.

These will be complemented by an exceptional seminar on day 5 (Sept. 15th), whose title and abstract follow

Neutrinos are the least understood particles in the Standard Model and are thus an important portal for new physics to couple to the visible sector. The presence of yet-unknown interactions among neutrinos could affect their streaming history in the early Universe, leaving important clues on cosmological observables. Interestingly, a scenario in which the onset of neutrino free-streaming in the early Universe is delayed until close to the epoch of matter-radiation equality has been shown to provide a good fit to some cosmic microwave background (CMB) data, while being somewhat disfavored by Planck CMB polarization data. After summarizing the current observational situation, I will present new CMB-independent constraints on this scenario from the Full Shape of the galaxy power spectrum. Although this interacting neutrino scenario predicts significant changes to the linear matter power spectrum, we find that it can provide a good fit to the the galaxy power spectrum data. Crucially, we show that these data also display a modest preference for a delayed onset of neutrino free-streaming over the standard model of cosmology. This independently confirms the signal seen in CMB analyses and motivates the exploration of neutrino interaction models capable of reconciling all CMB, large-scale structure, and laboratory data. We will conclude by discussing important predictions that this scenario makes, including a significant suppression of structure in the Universe on subgalactic scales.

Summary: The early universe represents a unique arena where to test indirectly possible extensions of the Electroweak Standard Model up to energy regions not even reachable in the far future at the accelerators. This is due to the relevance of the elementary particle physics in shaping the present universe once a Hot Big Bang Model is assumed. In this series of lectures the main pillars of the modern cosmology will be reviewed paying particular attention to those phenomena like baryogenesis, primordial nucleosynthesis and relic abundances (Dark Matter and Cosmological Neutrino Background) where particle physics essentially rules the game. The comparison of the theoretical predictions with the astrophysical observations allows to scrutinise the viability of possible models.
