A primer on Higgs Effective Field Theory with Geometry
Rodrigo Alonso
These lecture notes, prepared for the 2022 QUC summer school at KIAS, provide an introduction to Higgs Effective Field Theory and the use of field geometry in Quantum Field Theory.…
On the effective action for scalars in a general manifold to any loop order
Rodrigo Alonso, Mia West
Functional methods and a derivative expansion are employed for laying out a procedure to compute the effective action to any loop order, for scalar fields parametrising an arbitrar…
On the road(s) to the Standard Model
Rodrigo Alonso, Mia West
Experimental measurements point at the Standard Model (SM) as the theory of electroweak symmetry breaking, but as we close in on our characterization the question arises of what li…
Prospects for direct CP tests of interactions
Rodrigo Alonso, Cristofero Fraser-Taliente, Chris Hays +1
We study the prospects for probing the CP structure of interactions using the decays of the lightest baryon formed in the quark's hadronization. The low yields of recon…
Kick-alignment: matter asymmetry sourced dark matter
Rodrigo Alonso, Jakub Scholtz
We investigate the possibility that the dark matter abundance is sourced by the baryon/lepton asymmetry of the early Universe. It turns out that a Goldstone field of a local classi…
Covariant derivative expansion for the renormalization of gravity
Rodrigo Alonso
The one loop UV divergences of Hilbert-Einstein gravity with a cosmological constant and spin 0, 1/2 and 1 matter are computed making use of a covariant derivative expansion and fu…
Lepton (non-) unversality in (flavor changing) neutral current B decays
Rodrigo Alonso
The following proceedings contain a theory perspective on the flavor changing neutral current anomalies reported by LHCb on the ratios
On amplitudes, resonances and the ultraviolet completion of gravity
Rodrigo Alonso, Alfredo Urbano
This letter constructs, making use of the on-shell spinor-helicity formalism, a possible ultraviolet completion of gravity following a "bottom-up" approach. The assumptions of loca…
Tau Polarimetry in B Meson Decays
Rodrigo Alonso, Jorge Martin Camalich, Susanne Westhoff
This article summarizes recent developments in decays. We explain how to extract the tau lepton's production properties from the kinematics of its decay product…
Scattering of light dark matter in atomic clocks
Peter Wolf, Rodrigo Alonso, Diego Blas
We present a detailed analysis of the effect of light Dark Matter (DM) on atomic clocks, for the case where DM mass and density are such that occupation numbers are low and DM must…
Exploring the ultra-light to sub-MeV dark matter window with atomic clocks and co-magnetometers
Rodrigo Alonso, Diego Blas, Peter Wolf
Particle dark matter could have a mass anywhere from that of ultralight candidates, eV, to scales well above the GeV. Conventional laboratory searches are sensi…
A clockwork solution to the flavor puzzle
Rodrigo Alonso, Adrian Carmona, Barry M. Dillon +3
We introduce a set of clockwork models of flavor that can naturally explain the large hierarchies of the Standard Model quark masses and mixing angles. Since the clockwork only con…
Renormalization group evolution of Higgs effective field theory
R. Alonso, K. Kanshin, S. Saa
The one-loop renormalization of the action for a set Dirac fermions and a set of scalars spanning an arbitrary manifold coupled via Yukawa-like and gauge interactions is presented.…
Wormholes and masses for Goldstone bosons
Rodrigo Alonso, Alfredo Urbano
There exist non-trivial stationary points of the Euclidean action for an axion particle minimally coupled to Einstein gravity, dubbed wormholes. They explicitly break the continuos…
Flavoured Local Symmetry and Anomalous Rare Decays
Rodrigo Alonso, Peter Cox, Chengcheng Han +1
We consider a flavoured gauge symmetry under which only the third generation fermions are charged. Such a symmetry can survive at low energies (~TeV) while still allowing for…
Anomaly-free local horizontal symmetry and anomaly-full rare B-decays
Rodrigo Alonso, Peter Cox, Chengcheng Han +1
The largest global symmetry that can be made local in the Standard Model + 3 while being compatible with Pati-Salam unification is . The gauge bosons…
Tau properties in from visible final-state kinematics
Rodrigo Alonso, Jorge Martin Camalich, Susanne Westhoff
In semi-leptonic decays with a tau lepton, features of the production process are imprinted on the tau helicity states. Since the tau momentum cannot be fully reconstructed exp…
The lifetime of the meson and the anomalies in
Rodrigo Alonso, Benjamín Grinstein, Jorge Martin Camalich
We investigate a new constraint on new-physics interpretations of the anomalies observed in decays making use of the lifetime of the meson. A constraint is…
Gauged Lepton Flavour
R. Alonso, E. Fernandez Martinez, M. B. Gavela +3
The gauging of the lepton flavour group is considered in the Standard Model context and in its extension with three right-handed neutrinos. The anomaly cancellation conditions lead…
Geometry of the Scalar Sector
Rodrigo Alonso, Elizabeth E. Jenkins, Aneesh V. Manohar
The -matrix of a quantum field theory is unchanged by field redefinitions, and so only depends on geometric quantities such as the curvature of field space. Whether the Higgs mu…
New physics in the kinematic distributions of
Rodrigo Alonso, Andrew Kobach, Jorge Martin Camalich
We investigate the experimentally-accessible kinematic distributions of the decays. Specifically, we study the decay rates as…
Sigma Models with Negative Curvature
Rodrigo Alonso, Elizabeth E. Jenkins, Aneesh V. Manohar
We construct Higgs Effective Field Theory (HEFT) based on the scalar manifold H^n, which is a hyperbolic space of constant negative curvature. The Lagrangian has a non-compact O(n,…
A Geometric Formulation of Higgs Effective Field Theory: Measuring the Curvature of Scalar Field Space
Rodrigo Alonso, Elizabeth E. Jenkins, Aneesh V. Manohar
A geometric formulation of Higgs Effective Field Theory (HEFT) is presented. Experimental observables are given in terms of geometric invariants of the scalar sigma model sector su…
Lepton universality violation and lepton flavor conservation in -meson decays
Rodrigo Alonso, Benjamín Grinstein, Jorge Martin Camalich
Anomalies in (semi)leptonic -meson decays present interesting patterns that might be revealing the shape of the new physics to come. In order to understand the experimental data…
