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…
The cost of an ALP solution to the neutral -anomalies
J. Bonilla, A. de Giorgi, B. Gavela +2
The neutral anomalies in decays are analysed in terms of the tree-level exchange of an axion-like-particle (ALP), within the effective field theory framework. The complete two-…
Double Higgs production at TeV colliders with Effective Field Theories: sensitivity to BSM Higgs couplings
D. Domenech, M. J. Herrero, R. A. Morales +1
In this work we study the production of two Higgs bosons at the two planned electron positron colliders with energies at the TeV domain, CLIC and ILC, within the context of Effecti…
Following the muon track of hierarchical sectors at LHCb
Xabier Cid Vidal, Titus Mombächer, Maria Ramos +1
This paper reports a study of the experimental signatures of hierarchical sectors beyond the Standard Model characterized by a flavor-violating heavy vector and a set of light pseu…
Towards the renormalisation of the Standard Model effective field theory to dimension eight: Bosonic interactions I
Mikael Chala, Guilherme Guedes, Maria Ramos +1
We compute the one-loop renormalisation group running of the bosonic Standard Model effective operators to order , with GeV being the electroweak scale and …
Unleashing the full power of LHCb to probe Stealth New Physics
Martino Borsato, Xabier Cid Vidal, Yuhsin Tsai +38
In this paper, we describe the potential of the LHCb experiment to detect Stealth physics. This refers to dynamics beyond the Standard Model that would elude searches that focus on…
Running in the ALPs
Mikael Chala, Guilherme Guedes, Maria Ramos +1
The couplings of axion-like particles are probed by different experiments across a huge range of energy scales. Accordingly, a consistent analysis of the corresponding constraints…
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…
Baryogenesis in Nonminimally Coupled Theories
M. P. L. P. Ramos, J. Páramos
We generalize the mechanism for gravitational baryogensis in the context of theories of gravity, including a nonminimal coupling between curvature and matter. In these model…
Real-time cosmography with redshift derivatives
C. J. A. P. Martins, M. Martinelli, E. Calabrese +1
The drift in the redshift of objects passively following the cosmological expansion has long been recognized as a key model-independent probe of cosmology. Here, we study the cosmo…
