  1. 49. Direct dark matter detection: leaving no stone unturned

  2. 38. A new scenario for singlet Dirac dark matter

    20 minutes talk

    We propose a new and compact realization of singlet Dirac dark matter within the WIMP framework. Our model replaces the standard Z_2​ stabilizing symmetry with a Z_6​, and uses spontaneous symmetry breaking to generate the dark matter mass, resulting in a much simplified scenario for Dirac dark matter. Concretely, we extend the Standard Model (SM) with just two new particles, a Dirac fermion...

    Relaxing the constraints on kinetic mixing is possible if the dark photon can couple directly to Dirac neutrinos

  4. 9. Probing low-reheating scenarios with minimal freeze-in dark matter
    Oscar Zapata

    20 minutes talk

    The parameter space of freeze-in dark matter through light dark photon (``minimal freeze-in dark matter'') is currently being probed by direct detection experiments through electron and nuclear recoil. We show the dark matter production in this scenario is sensitive to cosmic equation of state during reheating, from matter-like to kination-like. The main result is that low reheating scenario...

  5. 3. Dark matter production through gluon fusion mediated by the Higgs boson.
    Omar Rafael Torrijo Gonzalez (Universidad de Pamplona)
    02/12/2024, 16:45
    20 minutes talk

    In this presentation I will speak about the production of Dark matter through gluon fusion in the Standard Model and its minimal supersymmetric extensions. Specifically, We are going to discuss the calculation of the differential cross section at leading order for this process.

  6. 1. No-Go Dark Energy from Generalized SU(2) Proca Theories
    SANTIAGO GARCIA SERNA
    02/12/2024, 17:10
    20 minutes talk

    The Generalized SU(2) Proca theory, despite its potential in modeling various physical phenomena, fails to accurately describe dark energy. Using the Green's function formalism, approximate solutions demonstrate that dark energy solutions exist independently of the cosmic epoch. However, integrating Proca SU(2) dark energy with matter and radiation introduces singularities during the...

  7. 42. Collider feasibility of the dynamical scotogenic model
    Gustavo Ardila (Universidad de los Andes)
    02/12/2024, 17:35
    20 minutes talk

    In this talk we will first introduce the dynamical scotogenic model, which extends the usual radiative see-saw mechanism by one Z2 even scalar singlet that spontaneously breaks the U(1) lepton number symmetry, and explain some details of its phenomenology, emphasizing in the scalar sector. Then, we explain how this model can introduce neutrino masses compatible with the experimental...

  8. 44. Effective Models for Scalar Dark Matter with $Z_{2n}$ symmetries
    Simón González Gómez (Universidad de Antioquia)
    02/12/2024, 18:00
    10 minutes talk

    We present single and multi-component scalar dark matter scenarios explored via effective operators up to order $6$. For this, we utilize the mathematica code Sym2Int and generate the relevant operators of the Lagrangian up to the desired energy dimension. The operators are used as interaction inputs for the mathematica package FeynRules to produce the model files necessary for the...
