Vacuum Stability Conditions for Higgs Potentials with Triplets
Gilbert Moultaka, Michel C. Peyranère
Tree-level dynamical stability of scalar field potentials in renormalizable theories can in principle be expressed in terms of positivity conditions on quartic polynomial structure…
Probing the Higgs sector of Higgs Triplet Model at LHC
M. Chabab, M. C. Peyranère, L. Rahili
In this paper, we investigate the Higgs Triplet Model with hypercharge (HTM0), an extension of the Standard model, caracterised by a more involved scalar spectrum consistin…
On Naturalness in type II seesaw models and the heavy Higgs masses
Mohamed Chabab, Michel Capdequi Peyranere, Larbi Rahili
Here we study naturalness problem in a type II seesaw model, and show that the Veltman condition modified (mVC) by virtue of the additional scalar charged states is satisfied at on…
Degenerate Higgs bosons decays to and in the type II Seesaw Model
M. Chabab, M. C. Peyranere, L. Rahili
Using the most recent results of CMS and ATLAS, we study the Higgs decays to and in the scenario where the two CP even Higgs predicted by the type II seesaw model (HTM) a…
The Higgs Potential in the Type II Seesaw Model
A. Arhrib, R. Benbrik, M. Chabab +4
We perform in the type II seesaw setting, a detailed study of the dynamical features of the corresponding general renormalizable doublet/triplet Higgs potential that depends on fiv…
Kowalevski's analysis of the swinging Atwood's machine
Olivier Babelon, Michel Talon, Michel Capdequi Peyranère
We study the Kowalevski expansions near singularities of the swinging Atwood's machine. We show that there is a infinite number of mass ratios where such expansions exist wit…
Higgs decays in the Two Higgs Doublet Model: Large quantum effects in the decoupling regime
A. Arhrib, M. Capdequi Peyranere, W. Hollik +1
We study the Higgs-boson decays h0 -> b \bar{b}, h0 -> γγand h0 -> γZ within the framework of the Two Higgs Doublet Model (THDM) in the context of the decoupling regime, together w…
The quantum anharmonic oscillator in the Heisenberg picture and multiple scale techniques
Guy Auberson, Michel Capdequi Peyranere
Multiple scale techniques are well-known in classical mechanics to give perturbation series free from resonant terms. When applied to the quantum anharmonic oscillator, these techn…
Supersymmetric enhancement of associated ZA^0 production at e^+e^- colliders
A. G. Akeroyd, A. Arhrib, M. Capdequi Peyranère
We study the associated production of the A^0 neutral CP-odd Higgs boson with a neutral gauge boson Z in high energy e^+ e^- collisions at the one loop level. We present a detailed…
Associated H W Production in High Energy Collisions
A. Arhrib, M. Capdequi Peyranere, W. Hollik +1
We study the associated production of charged Higgs bosons with gauge bosons in high energy collisions at the one loop level. We present the analytical results and gi…
CP-odd Higgs boson production in association with Neutral gauge boson in High-Energy Collisions
A. G. Akeroyd, A. Arhrib, M. Capdequi Peyranère
We study the associated production of a CP-odd Higgs boson with a neutral gauge boson ( or photon) in high-energy collisions at the one-loop level in the framewo…
Scalar and Vector Mixings in Models
Michel Capdequi Peyranere
We study the possible mixings between gauge vector fields and scalar fields through their self-energies, arising in models with two Higgs doublets. We derive the relevant set of Sc…
Fermion and Sfermion Effects in charged Higgs pair production
A. Arhrib, M. Capdequi Peyranere, G. Moultaka
Top and bottom one loop corrections to are considered at NLC energies and found to be significantly large and negative over the full range of …
