1. A dark vector resonance at CLIC Supported by Conicyt (Chile) (PIA/ACT-1406, PIA/Basal FB0821), and by Fondecyt (Chile) (1160423) / Callender, Constanza ; Zerwekh, Alfonso R.
One of the main problems in particle physics is to understand the origin and nature of dark matter [...]

2. Dark matter from a vector field in the fundamental representation of SU(2)L / Sáez, Bastian Díaz ; Rojas-Abatte, Felipe ; Zerwekh, Alfonso R.
We explore an extension to the Standard Model which incorporates a vector field in the fundamental representation of SU(2)L as the only nonstandard degree of freedom. [...]

3. Modelling top partner-vector resonance phenomenology / Yepes, Juan ; Zerwekh, Alfonso
We have analysed the observable consequences of the interactions of spin-1 resonances coupled to the invariant fermionic currents that arise in an SO(5) Composite Higgs set-up. [...]

5. Corrections to (Pseudo)Scalars Decay into a Fermion Pair from Gravitational Torsion / Rojas Abatte, Felipe ; Zamora-Saa, Jilberto ; Castillo-Felisola, Oscar ; Díaz, Bastian ; et al
We study the contribution of the torsion-descendent four-fermion contact interaction to the decay width of a neutral (pseudo)scalar field into a fermion pair. [...]

7. Comments on the compatibility of thermodynamic equilibrium conditions with lattice propagators / Canfora, Fabrizio ; Giacomini, Alex ; Pais, Pablo ; Rosa, Luigi ; et al
In this paper the compatibility is analyzed of the non-perturbative equations of state of quarks and gluons arising from the lattice with some natural requirements for self-gravitating objects at equilibrium: the existence of an equation of state (namely, the possibility to define the pressure as a function of the energy density), the absence of superluminal propagation and Le Chatelier’s principle. [...]

8. The effect of composite resonances on Higgs decay into two photons / Cárcamo Hernández, A. E. ; Dib, Claudio O. ; Zerwekh, Alfonso R.
In scenarios of strongly coupled electroweak symmetry breaking, heavy composite particles of different spin and parity may arise and cause observable effects on signals that appear at loop levels. [...]
