Decoupling-limit consistency of the generalized SU(2) Proca theory
Alexander Gallego Cadavid, Carlos M. Nieto, Yeinzon Rodriguez
We study the consistency of the decoupling limit of the generalized SU(2) Proca theory (GSU2P). Namely, we study the healthiness of those terms whose analysis in the scalar limit w…
Towards the extended SU(2) Proca theory
Alexander Gallego Cadavid, Carlos M. Nieto, Yeinzon Rodriguez
In this work, we explore the construction of the most general vector-tensor theory with an SU(2) global symmetry in the vector sector as a proposal for a modified theory of gravity…
An asymptotically safe SU(5) GUT
M. Fabbrichesi, C. M. Nieto, A. Tonero +1
We minimally extend the Standard Model field content by adding new vector-like fermions at the TeV scale to allow gauge coupling unification at a realistic scale. We embed the mode…
Quark masses and mixings in minimally parameterized UV completions of the Standard Model
Reinhard Alkofer, Astrid Eichhorn, Aaron Held +3
We explore a simple parameterization of new physics that results in an ultraviolet complete gauge-quark sector of the Standard Model. Specifically, we add an antiscreening contribu…
In search of a UV completion of the Standard Model - 378.000 models that don't work
Daniele Barducci, Marco Fabbrichesi, Carlos M. Nieto +2
Asymptotically safe extensions of the Standard Model have been searched for by adding vector-like fermions charged under the Standard Model gauge group and having Yukawa-like inter…
Split Weyl transformations in quantum gravity
Carlos M. Nieto, Roberto Percacci, Vedran Skrinjar
We discuss various realizations of the Weyl group in the background field expansion of quantum gravity, in the presence of a cutoff, as required in applications of the functional r…
Massive Gauge-flation
Carlos M. Nieto, Yeinzon Rodriguez
Gauge-flation model at zeroth order in cosmological perturbation theory offers an interesting scenario for realizing inflation within a particle physics context, allowing us to inv…
Towards a proof of the equivalence between FRW background expansion and statistical isotropy
Yeinzon Rodriguez, L. Gabriel Gomez, Carlos M. Nieto
We will expose in this paper our advances towards a proof of the equivalence between FRW background expansion, during some period of time that contains primordial inflation, and th…
