The signal of ill-defined CPT weakening entanglement in the system
Jose Bernabeu, Francisco J. Botella, Nick E. Mavromatos +1
In the presence of quantum gravity fluctuations (space-time foam), the CPT operator may be ill-defined. Its perturbative treatment leads to a modification of the Einstein-Podolsky-…
Vector-like Quarks at the Origin of Light Quark Masses and Mixing
Francisco J. Botella, G. C. Branco, Miguel Nebot +2
We show how a novel fine-tuning problem present in the Standard Model can be solved through the introduction of a single flavour symmetry G, together with three quarks,…
Optimizing the octant search in long baseline neutrino experiments
C. R. Das, Jukka Maalampi, Joao Pulido +1
We study the possibility of determining the octant of the neutrino mixing angle , that is, whether or , in long baseline neutrino experi…
CP Violation in the scalar sector
D. Emmanuel-Costa, O. M. Ogreid, P. Osland +1
Models with an extended scalar sector may in principle provide new sources of CP violation originating in the scalar potential. One of the simplest ways to implement this idea is t…
On quasidegeneracy of Majorana neutrinos and the observed pattern of Leptonic mixing
M. N. Rebelo
We relate the observed pattern of leptonic mixing to the quaidegeneracy of three Majorana neutrinos. We show how lifting the degeneracy may lead to the measured value of …
What if the Masses of the First Two Quark Families are not Generated by the Standard Higgs?
F. J. Botella, G. C. Branco, M. N. Rebelo +1
We point out that, in the context of the SM, is expected to be large, of order one. The fact that mo…
Neutrino observables from predictive flavour patterns
Luis M. Cebola, David Emmanuel-Costa, Ricardo Gonzalez Felipe
We look for predictive flavour patterns of the effective Majorana neutrino mass matrix that are compatible with current neutrino oscillation data. Our search is based on the assump…
Spontaneous symmetry breaking in the -symmetric scalar sector
D. Emmanuel-Costa, O. M. Ogreid, P. Osland +1
We present a detailed study of the vacua of the -symmetric three-Higgs-doublet potential, specifying the region of parameters where these minimisation solutions occur. We work…
Gauge invariance and the physical spectrum in the two-Higgs-doublet model
Axel Maas, Leonardo Pedro
Observable states are gauge-invariant. In a non-Abelian gauge theory, these are necessarily composite operators. We investigate the spectrum of these operators in the two-Higgs-dou…
