Effects of heavy Majorana neutrinos on lepton flavor violating processes

G. Hernández-Tomé, J. I. Illana, G. López Castro +2

The observation of lepton flavor violating processes at colliders could be a clear signal of a non-minimal neutrino sector. We define a 5-parameter model with a pair of TeV fermion…

The Sun at TeV energies: gammas, neutrons, neutrinos and a cosmic ray shadow

Miguel Gutiérrez, Manuel Masip

High energy cosmic rays reach the surface of the Sun and start showers with thousands of secondary particles. Most of them will be absorbed by the Sun, but a fraction of the neutra…

Inverse see-saw neutrino masses in the Littlest Higgs model with T-parity

Francisco del Aguila, José Ignacio Illana, José María Perez-Poyatos +1

We show that the inverse see-saw is the most natural way of implementing neutrino masses in the Littlest Higgs model with T-parity. The three extra quasi-Dirac neutrinos are needed…

Quark-diquark models and baryonic fluctuations in QCD

E. Megias, E. Ruiz Arriola, L. L. Salcedo

We study the baryonic fluctuations of electric charge, baryon number and strangeness, by considering a realization of the Hadron Resonance Gas model in the light flavor sector of Q…

scattering from a similarity renormalization group perspective

María Gómez-Rocha, Enrique Ruiz Arriola

A Wilsonian approach based on the Similarity Renormalization Group to scattering is analyzed in the 00, 11 and 02 channels in momentum space up to a maximal CM energy of…

Probing Higgs couplings to light quarks via Higgs pair production

Lina Alasfar, Roberto Corral Lopez, Ramona Gröber

We consider the potential of the Higgs boson pair production process to probe the light quark Yukawa couplings. We show within an effective theory description that the prospects of…

Higgs phenomenology as a probe of sterile neutrinos

Jonathan M. Butterworth, Mikael Chala, Christoph Englert +2

Physics beyond the Standard Model can manifest itself as both new light states and heavy degrees of freedom. In this paper, we assume that the former comprise only a sterile neutri…

Modular Invariant Models of Lepton Masses at Levels 4 and 5

Juan Carlos Criado, Ferruccio Feruglio, Simon J. D. King

We explore alternative descriptions of the charged lepton sector in modular invariant models of lepton masses and mixing angles. In addition to the modulus, the symmetry breaking s…

Vector-like quarks with non-renormalizable interactions

Juan Carlos Criado, Manuel Perez-Victoria

We study the impact of the leading non-renormalizable terms in the effective field theory that describes general extensions of the Standard Model with vector-like quarks. Dropping…

Towards a reliable effective field theory of inflation

Mar Bastero-Gil, Arjun Berera, Rudnei O. Ramos +1

We present the first quantum field theory model of inflation that is renormalizable in the matter sector, with a super-Hubble inflaton mass and sub-Planckian field excursions, whic…

Weak production of strange baryons off the nucleon

M. Rafi Alam, I. Ruiz Simo

The charged current Cabibbo-supressed associated production off the nucleon induced by anti-neutrinos is studied at low and intermediate energies. The non-resonant terms are…

Probes of the Standard Model effective field theory extended with a right-handed neutrino

Julien Alcaide, Shankha Banerjee, Mikael Chala +1

If neutrinos are Dirac particles and, as suggested by the so far null LHC results, any new physics lies at energies well above the electroweak scale, the Standard Model effective f…
