Cosmological Constant Problems and Renormalization Group
Ilya L. Shapiro, Joan Sola
The Cosmological Constant Problem emerges when Quantum Field Theory is applied to the gravitational theory, due to the enormous magnitude of the induced energy of the vacuum. The u…
LXCDM: a cosmon model solution to the cosmological coincidence problem?
Javier Grande, Joan Sola, Hrvoje Stefancic
We consider the possibility that the total dark energy (DE) of the Universe is made out of two dynamical components of different nature: a variable cosmological term, Lambda, and a…
Single top-quark production by direct supersymmetric flavor-changing neutral-current interactions at the LHC
Jaume Guasch, Wolfgang Hollik, Siannah Penaranda +1
Production of (electrically neutral) heavy-quark pairs, such as t{\bar c} and {\bar t}c, is extremely suppressed in the SM. In supersymmetric (SUSY) theories, such as the MSSM, the…
SUSY Higgs boson flavor-changing neutral currents at the LHC
Santi Bejar, Jaume Guasch, Joan Sola
We compute and analyze the Flavor-Changing Neutral Current (FCNC) interactions of Minimal Supersymmetric Standard Model Higgs bosons (h = h0, H0, A0) with heavy quarks (top and bot…
Cosmology with variable parameters and effective equation of state for Dark Energy
Joan Sola, Hrvoje Stefancic
A cosmological constant, Lambda, is the most natural candidate to explain the origin of the dark energy (DE) component in the Universe. However, due to experimental evidence that t…
