Heavy resonances and the oblique parameters S and T
Ignasi Rosell, Antonio Pich, Juan Jose Sanz-Cillero
It has been confirmed experimentally the existence of a mass gap between Standard Model (SM) and eventual Beyond Standard Model (BSM) fields. Therefore, the use of effective approa…
Electroweak mass difference of mesons
Antonio Pich, Arthur Platschorre, Mario Reig
We consider electroweak (EW) gauge boson corrections to the masses of pseudoscalar mesons to next to leading order (NLO) in and . The pion mass shift induced by the $Z…
Updated global fit of the aligned two-Higgs-doublet model with heavy scalars
Anirban Karan, Víctor Miralles, Antonio Pich
An updated global fit on the parameter-space of the Aligned Two-Higgs-Doublet model has been performed with the help of the open-source package HEPfit, assuming the Standard-Model…
Final-state interactions in the CP asymmetries of charm-meson two-body decays
Antonio Pich, Eleftheria Solomonidi, Luiz Vale Silva
Urgent theoretical progress is needed in order to provide an estimate in the Standard Model of the recent measurement by LHCb of direct CP violation in charm-meson two-body decays.…
The Euclidean Adler Function and its Interplay with and
M. Davier, D. Díaz-Calderón, B. Malaescu +3
Three different approaches to precisely describe the Adler function in the Euclidean regime at around are available: dispersion relations based on the hadronic…
Global fit on coloured scalars including the last W-boson mass measurement
V. Miralles, O. Eberhardt, H. Gisbert +2
We consider a simple extension of the electroweak theory, incorporating one doublet of colour-octet scalars with Yukawa couplings satisfying the principle of minimal flav…
Violations of Quark-Hadron Duality in Low-Energy Determinations of
Antonio Pich, Antonio Rodríguez-Sánchez
Using the spectral functions measured in decays, we investigate the actual numerical impact of duality violations on the extraction of the strong coupling. These effects are ti…
The strong coupling constant: State of the art and the decade ahead
D. d'Enterria, S. Kluth, G. Zanderighi +55
Theoretical predictions for particle production cross sections and decays at colliders rely heavily on perturbative Quantum Chromodynamics (QCD) calculations, expressed as an expan…
Workshop on Tau Lepton Physics: Anniversary
Antonio Pich
The first Workshop on Tau Lepton Physics took place at Orsay in 1990. The evolution of the field and some physics highlights are briefly described, following the presentations disc…
Heavy states and electroweak effective approaches
Ignasi Rosell, Antonio Pich, Juan José Sanz-Cillero
The existence of a mass gap between the Standard Model (SM) and possible new states encourages us to use effective field theories. Here we follow the non-linear realization of the…
Unveiling Hidden Physics at the LHC
Oliver Fischer, Bruce Mellado, Stefan Antusch +30
The field of particle physics is at the crossroads. The discovery of a Higgs-like boson completed the Standard Model (SM), but the lacking observation of convincing resonances Beyo…
Constraints on coloured scalars from global fits
Otto Eberhardt, Víctor Miralles, Antonio Pich
We consider a simple extension of the electroweak theory, incorporating one doublet of colour-octet scalars with Yukawa couplings satisfying the principle of minimal flav…
SU(3) analysis of four-quark operators: and vacuum matrix elements
Antonio Pich, Antonio Rodríguez-Sánchez
Hadronic matrix elements of local four-quark operators play a central role in non-leptonic kaon decays, while vacuum matrix elements involving the same kind of operators appear in…
Precision physics with inclusive QCD processes
Antonio Pich
The inclusive production of hadrons through electroweak currents can be rigorously analysed with short-distance theoretical tools. The associated observables are insensitive to the…
Electroweak effective theory and beyond Standard Model resonances
Juan Jose Sanz-Cillero, Antonio Pich, Ignasi Rosell
We consider a non-linear realization of the electroweak symmetry-breaking pattern to construct a low-energy effective theory, later extended by…
Global fits in the Aligned Two-Higgs-Doublet model
Otto Eberhardt, Ana Peñuelas Martínez, Antonio Pich
We present the results of a global fit to the Aligned Two-Higgs Doublet Model, assuming that there are no new sources of CP violation beyond the quark mixing matrix. We use the mos…
Challenges for tau physics at the TeraZ
Antonio Pich
The very high statistics, low backgrounds and clean back-to-back kinematics of a TeraZ facility would provide an optimal laboratory for precision measurements of the properties…
Constraining resonances by using the electroweak effective theory
Ignasi Rosell, Antonio Pich, Juan José Sanz-Cillero
In the light of the mass gap between Standard Model (SM) states and possible new particles, effective field theories are a suitable approach. We take on the non-linear realization…
The role of right-handed neutrinos in anomalies

Motivated by the persistent anomalies reported in the data, we perform a general model-independent analysis of these transitions, in the presence of light right-hand…
A bottom-up approach within the electroweak effective theory: constraining heavy resonances
Antonio Pich, Ignasi Rosell, Juan José Sanz-Cillero
The LHC has confirmed the existence of a mass gap between the known particles and possible new states. Effective field theory is then the appropriate tool to search for low-energy…
Rare kaon decays and CP violation

Owing to the strong suppression of flavour-changing neutral-current transitions in the Standard Model, rare kaon decays constitute a superb tool to constrain hypothetical new-physi…
