Two-flavor chirally imbalanced quark matter beyond large
André G. da Silva, Dyana C. Duarte, Ricardo L. S. Farias +3
We investigate a chirally imbalanced medium in the context of the two-flavor Nambu--Jona-Lasinio model using both the large- (LN) and beyond large- (BLN) approximations.…
No room for minimal monopole dark matter
Felix Brümmer, Giacomo Ferrante, Théodore Fischer +1
The magnetic monopole of a dark sector has been advocated as an appealing dark matter candidate. We revisit the computation of the monopole abundance , generated by a thermal…
Scale dependence improvement of the quartic scalar field thermal effective potential in the optimized perturbation theory
Lucas G. Câmara, Marcus Benghi Pinto, Rudnei O. Ramos
Perturbation theory, as well as most thermal field resummation methods widely used to study finite-temperature quantum field theories, presents a non-negligible renormalization sca…
Comparing strange and non-strange quark stars within resummed QCD at NLO
Tulio E. Restrepo, Jean-Loïc Kneur, Constança Providência +1
We employ the renormalization group optimized perturbation theory (RGOPT) resummation method to evaluate the equation of state (EoS) for strange () and non-strange ($N_f=2…
Two portals to GeV sterile neutrinos : dipole versus mixing
Enrico Bertuzzo, Michele Frigerio
Massive sterile neutrinos, also known as heavy neutral leptons, can have a mixing with active neutrinos, , as well as a dipole coupling to the photon, . We study the interpla…
Prospects for sub-EW-scale ALP searches via signatures at the LHC using jet substructure techniques
Amit Adhikary, Aoife Bharucha, Lorenzo Feligioni +1
The current Large Hadron Collider (LHC) data show no clear indication of new physics and only incremental improvements are anticipated at the energy frontier in the near future. Ho…
Muon collider probes of Majorana neutrino dipole moments and masses
Michele Frigerio, Natascia Vignaroli
Majorana neutrinos may have transitional dipole moments, which violate lepton number as well as lepton flavour. We estimate the sensitivity of future colliders to the electron-muon…
Cold Quark Matter: Renormalization Group Improvement at next-to-next-to leading order
Loïc Fernandez, Jean-Loïc Kneur
We extend previous next-to-next-to leading order (NNLO) calculations of the QCD pressure at zero temperature and non-zero baryonic densities using the renormalization group optimiz…
Accidentally light scalars from large representations
Felix Brümmer, Giacomo Ferrante, Michele Frigerio +1
In models with spontaneous symmetry breaking by scalar fields in large group representations, we observe that some of the scalar masses can be loop-suppressed with respect to the n…
MSSM-inflation revisited: Towards a coherent description of high-energy physics and cosmology
Gilles Weymann-Despres, Sophie Henrot-Versillé, Gilbert Moultaka +3
The aim of this paper is to highlight the challenges and potential gains surrounding a coherent description of physics from the high-energy scales of inflation down to the lower en…
SuSpect3: A C++ Code for the Supersymmetric and Higgs Particle Spectrum of the MSSM
Jean-Loic Kneur, Gilbert Moultaka, Michael Ughetto +2
We present the program SuSpect3 that calculates the masses and couplings of the Higgs and supersymmetric particles predicted by the Minimal Supersymmetric Standard Model (MSSM). Th…
The hMSSM with a Light Gaugino/Higgsino Sector: Implications for Collider and Astroparticle Physics
Giorgio Arcadi, Abdelhak Djouadi, Hong-Jian He +2
The hMSSM is a special parameterization of the minimal supersymmetric extension of the Standard Model (MSSM) in which the mass of the lightest Higgs boson is automatically set to t…
The Higgs Boson Mass as Fundamental Parameter of the Minimal Supersymmetric Standard Model
Rima El-Kosseifi, Jean-Loic Kneur, Gilbert Moultaka +1
In the Minimal Supersymmetric Standard Model (MSSM) the mass of the lightest neutral Higgs boson is determined by the supersymmetric parameters. In the MSSM the precisely meas…
Holographic models of composite Higgs in the Veneziano limit. Part II. Fermionic sector
Daniel Elander, Michele Frigerio, Marc Knecht +1
We continue our study of strongly-coupled, approximately scale-invariant gauge theories with a large number of flavours, which provide a suitable ultraviolet completion of the comp…
Effective comparison of neutrino-mass models
Rupert Coy, Michele Frigerio
New physics in the lepton sector may account for neutrino masses, affect electroweak precision observables, induce charged-lepton flavour violation, and shift dipole moments. The l…
All order resummed leading and next-to-leading soft modes of dense QCD pressure
Loïc Fernandez, Jean-Loïc Kneur
The cold and dense QCD equation of state (EoS) at high baryon chemical potential involves at order an all-loop summation of the soft mode cont…
Renormalization group optimized pressure at next-to-next-to-leading order
Loïc Fernandez, Jean-Loïc Kneur
We investigate the renormalization group optimized perturbation theory (RGOPT) at the next-to-next-to-leading order (NNLO) for the thermal scalar field theory. From comparing three…

Jean-Loïc Kneur, Marcus Benghi Pinto, Tulio E. Restrepo
We apply the renormalization group optimized perturbation theory (RGOPT) to evaluate the quark contribution to the QCD pressure at finite temperatures and baryonic densities, at ne…

Jean-Loïc Kneur, Marcus Benghi Pinto, Tulio E. Restrepo
The quark contribution to the QCD pressure, , is evaluated up to next-to-leading order (NLO) within the renormalization group optimized perturbation theory (RGOPT) resummation…
Vacuum Stability Conditions for Higgs Potentials with Triplets
Gilbert Moultaka, Michel C. Peyranère
Tree-level dynamical stability of scalar field potentials in renormalizable theories can in principle be expressed in terms of positivity conditions on quartic polynomial structure…
Holographic models of composite Higgs in the Veneziano limit. Part I. Bosonic sector
Daniel Elander, Michele Frigerio, Marc Knecht +1
We study strongly-coupled, approximately scale-invariant gauge theories, which develop a mass gap in the infrared. We argue that a large number of fermion flavours is most suitable…
Chiral Condensate and Spectral Density at full five-loop and partial six-loop orders of Renormalization Group Optimized Perturbation
Jean-Loic Kneur, André Neveu
We reconsider our former determination of the chiral quark condensate from the related QCD spectral density of the Euclidean Dirac operator, using our Re…
Confronting minimal freeze-in models with the LHC
G. Bélanger, N. Desai, A. Goudelis +8
We present a class of dark matter models, in which the dark matter particle is a feebly interacting massive particle (FIMP) produced via the decay of an electrically charged and/or…
