Dark showers from sneaky dark matter
Adrian Carmona, Fatemeh Elahi, Christiane Scherb +1
We present a minimal composite dark matter model, based on a dark sector with dark quarks and a heavy t-channel mediator. For , the dark flavor symmetry…
LHC EFT WG Note: Precision matching of microscopic physics to the Standard Model Effective Field Theory (SMEFT)
Sally Dawson, Admir Greljo, Kristin Lohwasser +16
This note gives an overview of the tools for the precision matching of ultraviolet theories to the Standard Model effective field theory (SMEFT) at the tree level and one loop. Sev…
The ALPs from the Top: Searching for long lived axion-like particles from exotic top decays
Adrian Carmona, Fatemeh Elahi, Christiane Scherb +1
We propose a search for long lived axion-like particles (ALPs) in exotic top decays. Flavour-violating ALPs appear as low energy effective theories for various new physics scenario…
Matchmakereft: automated tree-level and one-loop matching
Adrian Carmona, Achilleas Lazopoulos, Pablo Olgoso +1
We introduce matchmakereft, a fully automated tool to compute the tree-level and one-loop matching of arbitrary models onto arbitrary effective theories. Matchmakereft performs an…
The Forward Physics Facility: Sites, Experiments, and Physics Potential
Luis A. Anchordoqui, Akitaka Ariga, Tomoko Ariga +78
The Forward Physics Facility (FPF) is a proposal to create a cavern with the space and infrastructure to support a suite of far-forward experiments at the Large Hadron Collider dur…
Charming ALPs
Adrian Carmona, Christiane Scherb, Pedro Schwaller
Axion-like particles (ALPs) are ubiquitous in models of new physics explaining some of the most pressing puzzles of the Standard Model. However, until relatively recently, little a…
A warped scalar portal to fermionic dark matter
Adrian Carmona, Javier Castellano Ruiz, Matthias Neubert
We argue that extensions of the SM with a warped extra dimension, together with a new -odd scalar singlet, provide a natural explanation not only for the hierarchy pr…
Dynamical origin of flavor hierarchies in a warped extra dimension
Aqeel Ahmed, Adrian Carmona, Javier Castellano Ruiz +2
Extensions of the Standard Model featuring a warped extra dimension compactified on an orbifold, in which the fermions and gauge bosons live in the bulk of the f…
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…
Higgs Pair Production as a Signal of Enhanced Yukawa Couplings
Martin Bauer, Marcela Carena, Adrián Carmona
We present a non-trivial correlation between the enhancement of the Higgs-fermion couplings and the Higgs pair production cross section in two Higgs doublet models with a flavour s…
Recent Physics Anomalies - a First Hint for Compositeness?
Adrián Carmona, Florian Goertz
We scrutinize the recently further strengthened hints for new physics in semileptonic -meson decays, focusing on the 'clean' ratios of branching fractions and …
Exceptional Composite Dark Matter
Guillermo Ballesteros, Adrian Carmona, Mikael Chala
We study the dark matter phenomenology of non-minimal composite Higgs models with broken to the exceptional group . In addition to the Higgs, three pseudo-Nambu-Goldst…
A flavor-safe composite explanation of
Adrian Carmona, Florian Goertz
In these proceedings we discuss a flavor-safe explanation of the anomaly found in by LHCb, within the framework of compos…
Uncovering the relation of a scalar resonance to the Higgs boson
Adrian Carmona, Florian Goertz, Andreas Papaefstathiou
We consider the associated production of a scalar resonance with the standard model Higgs boson. We demonstrate via a realistic phenomenological analysis that couplings of such a r…
Les Houches 2015: Physics at TeV colliders - new physics working group report
G. Brooijmans, C. Delaunay, A. Delgado +78
We present the activities of the 'New Physics' working group for the 'Physics at TeV Colliders' workshop (Les Houches, France, 1-19 June, 2015). Our report includes new physics stu…
A 750 GeV graviton from holographic composite dark sectors
Adrian Carmona
We show that the 750 GeV di-photon excess can be interpreted as a spin-2 resonance arising from a strongly interacting dark sector featuring some departure from conformality. This…
The Diboson Excess: Experimental Situation and Classification of Explanations; A Les Houches Pre-Proceeding
Johann Brehmer, Gustaaf Brooijmans, Giacomo Cacciapaglia +21
We examine the `diboson' excess at TeV seen by the LHC experiments in various channels. We provide a comparison of the excess significances as a function of the mass of th…
Lepton Flavor and Non-Universality from Minimal Composite Higgs Setups
Adrian Carmona, Florian Goertz
We present a new class of models of lepton flavor in the composite Higgs framework. Following the concept of minimality, they lead to a rich phenomenology in good agreement with th…
Flavour, Electroweak Symmetry Breaking and Dark Matter: state of the art and future prospects
Giulia Ricciardi, Alexandre Arbey, Enrico Bertuzzo +12
With the discovery of the Higgs boson the Standard Model has become a complete and comprehensive theory, which has been verified with unparalleled precision and in principle might…
Diboson resonant production in non-custodial composite Higgs models
Adrian Carmona, Antonio Delgado, Mariano Quiros +1
We show that the recently reported excess in resonant diboson production can be explained in the context of non-custodial composite Higgs models. Dibosons are generated via the s-c…
Composite Dark Sectors
Adrian Carmona, Mikael Chala
We introduce a new paradigm in Composite Dark Sectors, where the full Standard Model (including the Higgs boson) is extended with a strongly-interacting composite sector with globa…
A naturally light Higgs without light Top Partners
Adrian Carmona, Florian Goertz
We demonstrate that the inclusion of a realistic lepton sector can relax significantly the upper bound on top partner masses in minimal composite Higgs models, induced by the light…
Higgs Production and Decay in Models of a Warped Extra Dimension with a Bulk Higgs
Paul R. Archer, Marcela Carena, Adrian Carmona +1
Warped extra-dimension models in which the Higgs boson is allowed to propagate in the bulk of a compact AdS space are conjectured to be dual to models featuring a partially com…
From Tevatron's top and lepton-based asymmetries to the LHC
Adrian Carmona, Mikael Chala, Adam Falkowski +4
We define a lepton-based asymmetry in semi-leptonic ttbar production at the LHC. We show that the ratio of this lepton-based asymmetry and the ttbar charge asymmetry, measured as a…
