Central exclusive production of and mesons in diffractive proton-proton collisions at the LHC and the nature of the pomeron
Piotr Lebiedowicz, Otto Nachtmann, Antoni Szczurek
Central exclusive production (CEP) of and mesons in proton-proton collisions at high-energies is discussed. At the LHC the main mechanism for the production of these meson…
Charm associated production of the pseudoscalar Higgs boson in the MCPM' at the LHC
Rafał Maciuła, Markos Maniatis, Otto Nachtmann +1
We discuss charm associated production of the pseudoscalar Higgs boson in the MCPM'. In our analysis we assume = 95.4 GeV, which corresponds to an enhancement obser…
CMS results for the production at the LHC: do they give a hint for a Higgs boson of the maximally CP symmetric two-Higgs-doublet model?
M. Maniatis, O. Nachtmann
Recent measurements of the CMS experiment at the LHC show possibly, with about 3 significance, a resonance in di-photon events with an invariant mass of 95.4 GeV. If this reson…
Stability and symmetry breaking in the general n-Higgs-doublet model
M. Maniatis, O. Nachtmann
For potentials with n-Higgs-boson doublets stability, electroweak symmetry breaking, and the stationarity equations are discussed in detail. This is done within the bilinear formal…
Stability and symmetry breaking in the general three-Higgs-doublet model
M. Maniatis, O. Nachtmann
Stability, electroweak symmetry breaking, and the stationarity equations of the general three-Higgs-doublet model (3HDM) where all doublets carry the same hypercharge are discussed…
Symmetries and renormalisation in two-Higgs-doublet models
M. Maniatis, O. Nachtmann
We discuss the classification of symmetries and the corresponding symmetry groups in the two-Higgs-doublet model (THDM). We give an easily useable method how to determine the symme…
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)…
On the phenomenology of a two-Higgs-doublet model with maximal CP symmetry at the LHC - synopsis and addendum
M. Maniatis, A. von Manteuffel, O. Nachtmann
Predictions for LHC physics are given for a two-Higgs-doublet model having four generalized CP symmetries. In this maximally-CP-symmetric model (MCPM) the first fermion family is,…
On the phenomenology of a two-Higgs-doublet model with maximal CP symmetry at the LHC, II: radiative effects
M. Maniatis, O. Nachtmann
The processes proton + antiproton -> gamma + heavy-flavour jet(s) + X and proton + proton -> gamma + heavy-flavour jet(s) + X are studied in the framework of a special two-Higgs-do…
On the phenomenology of a two-Higgs-doublet model with maximal CP symmetry at the LHC
M. Maniatis, O. Nachtmann
Predictions for LHC physics are worked out for a two-Higgs-doublet model having four generalized CP symmetries. In this maximally-CP-symmetric model (MCPM) the first fermion family…
Anomalous gauge-boson couplings and the Higgs-boson mass
O. Nachtmann, F. Nagel, M. Pospischil
We study anomalous gauge-boson couplings induced by a locally SU(2) x U(1) invariant effective Lagrangian containing ten operators of dimension six built from the boson fields of t…
Flavour Dynamics with General Scalar Fields
W. Bernreuther, O. Nachtmann
We consider a spontaneously broken gauge theory based on the standard model (SM) group G = SU(2) x U(1) with scalar fields that carry arbitrary representations of G, and we investi…
