While advocacy was essential to establishing the field of marriage and family therapy, at present a social and political advocacy skill set is lacking for the typical marriage and family therapist (MFT). This article reviews the importance of being active in social and political advocacy and highlights the attributes of MFTs’ professional identity that uniquely position us for success in these areas. Other mental health fields’ pedagogical approaches to training and education are explored, and recommendations are made for how MFTs can begin to increase their competency in advocacy. Ideas for incorporating advocacy into a professional identity are presented for MFTs at every level of professional experience. Finally, the concept self‐of‐the‐advocate is introduced and discussed.
We consider general fermi-phobic scenarios in which excess events in diphoton or WW/ZZ resonances may be seen at LHC. These Higgs like signals do not necessarily suggest that the new resonance is a particle with Yukawa couplings nor do we know that it is responsible for electroweak symmetry breaking. We can, however, extract two facts from it, this particle couples to pairs of SU(2) and U(1) gauge bosons and it must be a scalar, pseudoscalar, or tensor. We consider the signals of general operators up to effective dimension 5 in which a new scalar, psuedo-scalar, or tensor particle may couple to pairs of standard model gauge bosons. This particle may or may not be charged under the standard model gauge groups, and may be produced via gluon fusion or EW vector boson fusion. I. INTRODUCTIONThe Standard Model (SM) has been amazingly successful in describing fundamental interactions however, it remains incomplete. The Higgs boson is most likely the particle responsible for electroweak symmetry breaking, though it has yet to be discovered. The Higgs mass is not a known quantity however, its production cross sections and branching fractions to SM particles are well known [1][2][3]. At the LHC both the production and the decay of the Higgs boson are dominated by processes in which the Higgs has effective couplings to pairs of SM gauge bosons. While Higgs production is dominated by gluon fusion [4], it does not couple directly to gluons but has a large effective coupling them through a loop of heavy quarks. At low masses (m H 130GeV), the Higgs decays predominately to b b however, large QCD backgrounds at LHC make this channel difficult to see. Thus, the Higgs decays to pairs of electroweak gauge bosons are crucial for Higgs searches. In fact one of the most important channels for Higgs discovery is h → γγ. Again, the Higgs does not couple directly to photons but it has an effective coupling brought about by loops of charged W bosons and heavy third generation quarks. In fact, decays to weak boson pairs become dominate once we reach the kinematic threshold since the leading term in the partial width of Higgs to diboson is cubic in Higgs mass versus linear in Higgs mass for partial width to fermion pairs. LEP, Tevatron, and now ATLAS and CMS have been chipping away at Higgs mass parameter space leaving only a small window for the SM Higgs to hide [5][6]. Recent search results from both ATLAS and CMS have reported a small excess in the WW channel and a slightly larger excess in the ZZ and γγ channels around 125GeV [7][8]. While this excess may be the first hint at the SM Higgs, it is not yet a discovery.However, seeing a mass resonance in a diboson channel does not necessarily mean that the particle being produced is a Higgs. One would still be lacking evidence that the particle has the standard Yukawa couplings, or that it is responsible for electro-weak symmetry breaking. In fact, if a mass resonance is seen in and EW boson channel the new state may not have effective couplings to gluons as the Higgs does, unlike the Higg...
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
