A bstractThe real projective plane is a compact, non-orientable orbifold of Euler characteristic 1 without boundaries, which can be described as a twisted Klein bottle. We shortly review the motivations for choosing such a geometry among all possible two-dimensional orbifolds, while the main part of the study will be devoted to dark matter study and limits in Universal Extra Dimensional (UED) models based on this peculiar geometry. In the following we consider such a UED construction based on… 
Dark matter and localised fermions from spherical orbifolds?
A bstractWe study a class of six-dimensional models based on positive curvature surfaces (spherical 2-orbifolds) as extra-spaces. Using the Newman-Penrose formalism, we discuss the particle spectrum
Electroweak Kaluza-Klein dark matter
A bstractIn models with universal extra dimensions (UED), the lightest Kaluza-Klein excitation of neutral electroweak gauge bosons is a stable, weakly interacting massive particle and thus is a
Towards Kaluza-Klein Dark Matter on nilmanifolds
A bstractWe present a first study of the field spectrum on a class of negatively-curved compact spaces: nilmanifolds or twisted tori. This is a case where analytical results can be obtained, allowing
Even tiers and resonances on the real projective plane
A bstractIn this work we focus on various phenomenological aspects of the lightest even tiers, (2, 0) and (0, 2), in models based on a Real Projective Plane in 6 dimensions. We discuss the spectrum
Higgs quartic coupling and neutrino sector evolution in 2UED models
Two compact universal extra-dimensional models are an interesting class of models for different theoretical and phenomenological issues, such as the justification of having three standard model
Higgs couplings beyond the standard model
A bstractWe consider the Higgs boson decay processes and its production, and provide a parameterisation tailored for testing models of new physics beyond the Standard Model. We also compare our
Higgsphobic and fermiophobic Z’ as a single dark matter candidate
A bstractA spin-1 Z’ particle as a single dark matter candidate is investigated by assuming that it does not directly couple to the Higgs boson and standard model fermions and does not mix with the
Status report on universal extra dimensions after LHC8
Although they do not address the hierarchy problem, models with Universal Extra Dimensions have attracted a lot of attention as simple benchmark models characterized by small mass splittings and a
A review on non-minimal universal extra dimensions
We report on the current status of non-minimal universal extra dimension (NMUED) models. Our emphasis is on the possible extension of the minimal UED (MUED) model by allowing bulk masses and boundary
Search for New Phenomena in Top-Antitop Quarks Final States with Additional Heavy-Flavour Jets with the ATLAS Detector
In the particle physics, in order to explain the shortcomings in the Standard Model (SM), physics models beyond the Standard Model (BSM) have been proposed. Some of them predict the existence of new

The Real Projective Plane is the lowest dimensional orbifold which, when combined with the usual Minkowski space-time, gives rise to a unique model in six flat dimensions possessing an exact Kaluza

Abstract We propose a six-dimensional Universal Extra Dimensions (UED) model compactified on a real projective plane RP 2 , a two-sphere with its antipodal points being identified. We utilize the
