Running beyond ALPs: shift-breaking and CP-violating effects
Supratim Das Bakshi, Jonathan Machado-Rodríguez, Maria Ramos
We compute the renormalization group equations (RGEs) of the Standard Model effective field theory (EFT) extended with a real scalar singlet, up to dimension-five and one-loop accu…
The QCD axion sum rule
Belén Gavela, Pablo Quílez, Maria Ramos
We demonstrate that the true QCD axion that solves the strong CP problem can be found in all generality outside the customary standard QCD band, with QCD being the sole source of P…
Neutral -anomalies from an scalar exchange
Jesus Bonilla, Arturo de Giorgi, Maria Ramos
The neutral -anomalies are analysed in terms of the tree-level exchange of a (pseudo)scalar gauge singlet . Solutions to both central bin anomalies are found wi…
Effective field theory for vector-like leptons and its collider signals
Mikael Chala, Paweł Kozów, Maria Ramos +1
We argue that in models with several high scales; e.g. in composite Higgs models or in gauge extensions of the Standard Model (SM), vector-like leptons can be likely produced in a…
Composite dark matter phenomenology in the presence of lighter degrees of freedom
Maria Ramos
Scalar singlet dark matter in anomaly-free composite Higgs models is accompanied by exotic particles to which the dark matter annihilates. The latter can therefore freeze out even…
Novel -decay signatures of light scalars at high energy facilities
Andrew Blance, Mikael Chala, Maria Ramos +1
We study the phenomenology of light scalars of masses and coupling to heavy flavour-violating vector bosons of mass . For few GeV, this scenario…
