Abelian symmetries in the two-Higgs-doublet model with fermions
P. M. Ferreira, Joao P. Silva
We classify all possible implementations of an abelian symmetry in the two-Higgs-doublet model with fermions. We identify those symmetries which are consistent with non-vanishing q…
A Constraint On the Integrated Mass Power Spectrum out to z = 1100 from Lensing of the Cosmic Microwave Background
Joseph Smidt, Asantha Cooray, Alexandre Amblard +4
The temperature fluctuations and polarization of the Cosmic Microwave Background (CMB) are now a well-known probe of the Universe at an infant age of 400,000 years. During the tran…
Phase diagrams of binary mixtures of patchy colloids with distinct numbers of patches: The network fluid regime
Daniel de las Heras, José M. Tavares, Margarida M. Telo da Gama
We calculate the network fluid regime and phase diagrams of binary mixtures of patchy colloids, using Wertheim's first order perturbation theory and a generalization of Flory-Stock…
Extracting the Omega- electric quadrupole moment from lattice QCD data
G. Ramalho, M. T. Pena
The Omega- has an extremely long lifetime, and is the most stable of the baryons with spin 3/2. Therefore the Omega- magnetic moment is very accurately known. Nevertheless, its ele…
Geometric picture of generalized-CP and Higgs-family transformations in the two-Higgs-doublet model
P. M. Ferreira, Howard E. Haber, M. Maniatis +2
In the two-Higgs-doublet model (THDM), generalized-CP transformations (phi_i--> X_{ij} phi_j^* where X is unitary) and unitary Higgs-family transformations (phi_i--> U_{ij} phi_j)…
Tetraquark resonances with the triple flip-flop potential, decays in the cherry in a broken glass approximation
Pedro Bicudo, Marco Cardoso
We develop a unitarized formalism to study tetraquarks using the triple flip-flop potential, which includes two meson-meson potentials and the tetraquark four-body potential. This…
