The evolution of vacuum states and phase transitions in 2HDM during cooling of Universe
I. F. Ginzburg, I. P. Ivanov, K. A. Kanishev
We consider the evolution of the ground state in the Two Higgs Doublet Model during cooling down of the Universe after the Big Bang. Different regions in the space of free paramete…
The Total Cross Section at the LHC: Models and Experimental Consequences
J. R. Cudell
I review the predictions of the total cross section for many models, and point out that some of them lead to the conclusion that the standard experimental analysis may lead to syst…
Light-front interpretation of Proton Generalized Polarizabilities
M. Gorchtein, C. Lorcé, B. Pasquini +1
We extend the recently developed formalism to extract light-front quark charge densities from nucleon form factor data to the deformations of these quark charge densities when appl…
Higgs masses of the general 2HDM in the Minkowski-space formalism
A. Degee, I. P. Ivanov
We study the masses of the Higgs bosons in the most general two-Higgs-doublet model in a basis-independent approach. We adapt the recently developed Minkowski-space formalism to th…
Can Y(4140) be a tetraquark ?
Fl. Stancu
In this exploratory study the spectrum of tetraquarks of type is calculated within a simple quark model with chromomagnetic interaction and effective quark mass…
Comparative analysis of large Nc QCD and quark model approaches to baryons
F. Buisseret, C. Semay, Fl. Stancu +1
We show that a remarkable compatibility exists between the results of a potential model with constituent quarks and the 1/Nc expansion mass formula for strange and nonstrange baryo…
