Numerical study of the Schwinger effect in axion inflation
Yann Cado, Mariano Quirós
Previous studies demonstrate that the inflaton, when coupled to the hypercharge Chern-Simons density, can source an explosive production of helical hypermagnetic fields. Then, in t…
LHC search strategy for squarks in higgsino-LSP scenarios with leptons and -jets in the final state
Ernesto Arganda, Antonio Delgado, Roberto A. Morales +1
The higgsino Lightest Supersymmetric Particle (LSP) scenario opens up the possibility of decays of strongly produced particles to an intermediate neutralino, due to the Yukawa-supp…
Baryogenesis from combined Higgs - scalar field inflation
Yann Cado, Mariano Quirós
We study a modification of the Higgs inflation scenario where we introduce an extra scalar , with mass , coupled to the Ricci scalar as , and mixed with the Higgs fie…
Hunting Squarks in Higgsino LSP scenarios at the LHC
Ernesto Arganda, Antonio Delgado, Roberto A. Morales +1
The assumption that strongly interacting sparticles will decay directly to the LSP plus jets breaks down in situations where those decays are Yukawa suppressed. That occurs when pr…
Search strategy for gluinos at the LHC with a Higgs boson decaying into tau leptons
Ernesto Arganda, Antonio Delgado, Roberto A. Morales +1
The possibility in supersymmetric scenarios that the dark matter candidate is a Higgsino-like neutralino means that its production can be associated with Higgs bosons. Taking advan…
Novel Higgsino Dark Matter Signatures at the LHC
Ernesto Arganda, Antonio Delgado, Roberto A. Morales +1
In the LHC searches for gluinos it is usually assumed that they decay predominantly into the lightest neutralino plus jets. In this work we perform a proof-of-concept collider anal…
