-mediated Majorana dark matter: suppressed direct-detection rate and complementarity of LHC searches
T. Alanne, F. Bishara, J. Fiaschi +3
We study the direct-detection rate for axial-vectorial dark matter scattering off nuclei in an invariant effective theory and compare it agains…
Pseudo-Goldstone dark matter: gravitational waves and direct-detection blind spots
Tommi Alanne, Nico Benincasa, Matti Heikinheimo +4
Pseudo-Goldstone dark matter is a thermal relic with momentum-suppressed direct-detection cross section. We study the most general model of pseudo-Goldstone dark matter arising fro…
Model-independent constraints with extended dark matter EFT
Tommi Alanne, Giorgio Arcadi, Florian Goertz +2
We systematically explore the phenomenology of the recently proposed extended dark matter effective field theory (\eDMEFT), which allows for a consistent effective description of D…
A fresh look at the gravitational-wave signal from cosmological phase transitions
Tommi Alanne, Thomas Hugle, Moritz Platscher +1
Many models of physics beyond the Standard Model predict a strong first-order phase transition (SFOPT) in the early Universe that leads to observable gravitational waves (GWs). In…
Axiflavon-Higgs Unification
Tommi Alanne, Simone Blasi, Florian Goertz
In this talk, a unified model of scalar particles that addresses the flavour hierarchies, solves the strong CP problem, delivers a dark matter candidate, and radiatively triggers e…
A critical look at -function singularities at large
Tommi Alanne, Simone Blasi, Nicola Andrea Dondi
We propose a self-consistency equation for the -function for theories with a large number of flavours, , that exploits all the available information in the Wilson-Fisher crit…
Bubble-resummation and critical-point methods for -functions at large
Tommi Alanne, Simone Blasi, Nicola Andrea Dondi
We investigate the connection between the bubble-resummation and critical-point methods for computing the -functions in the limit of large number of flavours, , and show that…
Direct and indirect probes of Goldstone dark matter
Tommi Alanne, Matti Heikinheimo, Venus Keus +2
There exists a general model framework where dark matter can be a vanilla WIMP-like thermal relic with a mass of (100 GeV), but it still escapes direct detection. This ha…
Low-scale leptogenesis assisted by a real scalar singlet
Tommi Alanne, Thomas Hugle, Moritz Platscher +1
Standard thermal leptogenesis in the type-I seesaw model requires very heavy right-handed neutrinos (RHNs). This makes it hard to probe this scenario experimentally and results in…
Dark matter in (partially) composite Higgs models
Tommi Alanne, Diogo Buarque Franzosi, Mads T. Frandsen +1
We construct composite and partially composite Higgs models with complex pseudo-Nambu--Goldstone (pNGB) dark matter states from four-dimensional gauge-Yukawa theories with strongly…
The abelian gauge-Yukawa -functions at large
Tommi Alanne, Simone Blasi
We study the impact of the Yukawa interaction in the large- limit to the abelian gauge theory. We compute the coupled -functions for the system in a closed form at $\mathca…
A Common Source for Scalars: Axiflavon-Higgs Unification
Tommi Alanne, Simone Blasi, Florian Goertz
We propose a unified model of scalar particles that addresses the flavour hierarchies, solves the strong CP problem, delivers a dark matter candidate, and provides the trigger for…
The -function for Yukawa theory at large
Tommi Alanne, Simone Blasi
We compute the -function for a massless Yukawa theory in a closed form at the order in the spirit of the expansion in a large number of flavours . We f…
Classification of NLO operators for composite Higgs models
T. Alanne, N. Bizot, G. Cacciapaglia +1
We provide a general classification of template operators, up to next-to-leading order, that appear in chiral perturbation theories based on the two flavour patterns of spontaneous…
Extended Dark Matter EFT
Tommi Alanne, Florian Goertz
Conventional approaches to describe dark matter phenomenology at collider and (in)direct detection experiments in the form of dark matter effective field theory or simplified model…
Partially composite Higgs models: Phenomenology and RG analysis
Tommi Alanne, Diogo Buarque Franzosi, Mads T. Frandsen +3
We study the phenomenology of partially composite-Higgs models where electroweak symmetry breaking is dynamically induced, and the Higgs is a mixture of a composite and an elementa…
A partially composite Goldstone Higgs
Tommi Alanne, Diogo Buarque Franzosi, Mads T. Frandsen
We consider a model of dynamical electroweak symmetry breaking with a partially composite Goldstone Higgs. The model is based on a strongly-interacting fermionic sector coupled to…
Neutrino mass generation and leptogenesis via pseudo-Nambu-Goldstone Higgs portal
Tommi Alanne, Aurora Meroni, Kimmo Tuominen
We consider an extension of the Standard Model with the global symmetry breaking pattern SO(5)/SO(4), where the Higgs boson arises as a pseudo-Nambu-Goldstone boson. The scalar con…
Inflation and pseudo-Goldstone Higgs boson
Tommi Alanne, Francesco Sannino, Tommi Tenkanen +1
We consider inflation within a model framework where the Higgs boson arises as a pseudo-Goldstone boson associated with the breaking of a global symmetry at a scale significantly l…
Vacuum alignment and radiatively induced Fermi scale
Tommi Alanne
We extend the discussion about vacuum misalignment by quantum corrections in models with composite pseudo-Goldstone Higgs boson to renormalisable models with elementary scalars. As…
Radiatively induced Fermi scale and unification
Tommi Alanne
We propose a framework, where the hierarchy between the unification and the Fermi scale emerges radiatively. This work tackles the long-standing question about the connection betwe…
Baryogenesis in the two doublet and inert singlet extension of the Standard Model
Tommi Alanne, Kimmo Kainulainen, Kimmo Tuominen +1
We investigate an extension of the Standard Model containing two Higgs doublets and a singlet scalar field (2HDSM). We show that the model can have a strongly first-order phase tra…

We systematically elucidate differences and similarities of the vacuum alignment issue in composite and renormalizable elementary extensions of the Standard Model featuring a pseud…
Testing a dynamical origin of Standard Model fermion masses
Tommi Alanne, Diogo Buarque Franzosi, Mads T. Frandsen
We discuss a test of the Standard Model fermion mass origin in models of dynamical electroweak symmetry breaking. The couplings of composite pseudoscalar resonances to top quarks a…
