The Protophobic Light Vector Boson as a Mediator to the Dark Sector
Teppei Kitahara,
Yasuhiro Yamamoto
(Submitted on 6 Sep 2016)
Observation of a protophobic 16.7 MeV vector boson has been reported by a 8Be nuclear transition experiment. Such a new particle could mediate between the Standard Model and a dark sector which includes the dark matter. In this Letter, we show some simple models which satisfy the thermal relic abundance under the current experimental bounds from the direct and the indirect detections. In a model, it is found that an appropriate self-scattering cross section to solve the small scale structure puzzles can be achieved.

The new interaction suggested by the anomalous 8Be transition sets a rigorous constraint on the mass range of dark matter
Lian-Bao Jia,
Xue-Qian Li
(Submitted on 18 Aug 2016)
The WIMPs are considered one of the most favorable dark matter (DM) candidates, but as the upper bound on the interaction between DM and standard model (SM) particles obtained by the upgraded facilities for direct detection of DM gets lower and lower. Researchers turn their attention to search for less massive DM candidates, i.e. light dark matter of MeV scale. The recently measured anomalous transition in 8Be suggests that there exists a vectorial boson which may mediate the interaction between DM and SM particles. Based on this scenario, we combine the relevant cosmological data to constrain the mass range of DM, and have found that there exists a model parameter space where the requirements are satisfied, a range of 10.4≲mϕ≲16.7 MeV for scalar DM, and 13.6≲mV≲16.7 MeV for vectorial DM is demanded. Then a possibility of directly detecting such light DM particles at the Earth detector via the DM-electron scattering is briefly studied in this framework.

But, the Standard Model refuses to answer our questions: Why is electroweak symmetry broken ? Can we calculate the
Higgs mass, or the
Higgs potential ?
Minimal Composite Higgs Models at the LHC

We consider composite Higgs models where the Higgs is a pseudo-Nambu Goldstone boson arising from the spontaneous breaking of an approximate global symmetry by some underlying strong dynamics. We focus on the SO(5) -> SO(4) symmetry breaking pattern, assuming the partial compositeness paradigm. We study the consequences on Higgs physics of the fermionic representations produced by the strong dynamics, that mix with the Standard Model (SM) degrees of freedom. We consider models based on the lowest-dimensional representations of SO(5) that allow for the custodial protection of the Z -> b b coupling, i.e. the 5, 10 and 14. We find a generic suppression of the gluon fusion process, while the Higgs branching fractions can be enhanced or suppressed compared to the SM. Interestingly, a precise measurement of the Higgs boson couplings can distinguish between different realizations in the fermionic sector, thus providing crucial information about the nature of the UV dynamics.

The Composite Nambu-Goldstone Higgs

(Submitted on 5 Jun 2015 (
v1), last revised 11 Nov 2015 (this version, v2))
The composite Higgs scenario, in which the Higgs emerges as a composite pseudo-Nambu-Goldstone boson, is extensively reviewed in these Notes. The material is presented in a pedagogical fashion, with great emphasis on the conceptual and technical foundations of the construction. A comprehensive summary of the flavor, collider and electroweak precision phenomenology is also presented.

The Technicolor Higgs in the Light of LHC Data

We consider scenarios in which the 125 GeV resonance observed at the Large Hadron Collider is a Technicolor (TC) isosinglet scalar, the TC Higgs. By comparison with quantum chromodynamics, we argue that the couplings of the TC Higgs to the massive weak bosons are very close to the Standard Model (SM) values. The couplings to photons and gluons are model-dependent, but close to the SM values in several TC theories. The couplings of the TC Higgs to SM fermions are due to interactions beyond TC, such as Extended Technicolor: if such interactions successfully generate mass for the SM fermions, we argue that the couplings of the latter to the TC Higgs are also SM-like.
We suggest a generic parameterization of the TC Higgs interactions with SM particles that accommodates a large class of TC models, and we perform a fit of these parameters to the Higgs LHC data. The fit reveals regions of parameter space where the form factors are of order unity and consistent with data at the 95% CL, in agreement with expectations in TC theories. This indicates that the discovered Higgs boson is consistent with the TC Higgs hypothesis for several TC theories.
