Abstract

We explore the observable consequences of supersymmetry, under the assumption that it is broken spontaneously at energies of order 300 GeV. Theories of this sort tend automatically to obey a global R symmetry, which presents us with a choice among phenomenologically unacceptable alternatives. If the R symmetry is broken by scalar vacuum expectation values of order 300 GeV, there will be a semiweakly coupled light Goldstone boson, similar to an axion. If it is not broken by such vacuum expectation values but is broken by quantum-chromodynamic (QCD) anomalies, then there will be a light ninth pseudoscalar meson. If it is not broken by QCD anomalies, then the asymptotic freedom of QCD is lost at high energies, killing the hope of an eventual meeting of the electroweak and strong couplings within the regime of validity of perturbation theory. We also confront the problem of an uncomfortably light gluino. A general analysis of gaugino masses shows that the gluino mass is at most of order 1 GeV, and in many cases much less.

Status of weak scale supersymmetry after LHC Run 2 and ton-scale noble liquid WIMP searches

Journal Article Baer, Howard; Barger, Vernon; Sengupta, Dibyashree; ... - European Physical Journal. Special Topics

After completion of LHC Run 2, the ATLAS and CMS experiments had collected of order 139 fb^–1 of data at √s = 13 TeV. While discovering a very Standard Model-like Higgs boson of mass m_h ≃ 125 GeV, no solid signal for physics beyond the Standard Model has emerged so far at LHC. In addition, no WIMP signals have emerged so far at ton-scale noble liquid WIMP search experiments. For the case of weak scale supersymmetry (SUSY), which is touted as a simple and elegant solution to the gauge hierarchy problem and likely low energy limit of compactified string theory,more »« less

Supersymmetry, naturalness, and dynamical supersymmetry breaking

Journal Article Dine, M; MacIntire, D - Physical Review, D (Particles Fields); (United States)

Models with dynamical supersymmetry (SUSY) breaking have the potential to solve many of the naturalness problems of hidden sector supergravity models. We review the argument that in a generic supergravity theory in which supersymmetry is {ital dynamically} broken in the hidden sector, only tiny Majorana masses for gauginos are generated. This situation is similar to that of theories with continuous {ital R} symmetries, for which Hall and Randall have suggested that gluino masses could arise through mixings with an octet of chiral fields. We note that, in hidden sector models, such mixing can only occur if the auxiliary {ital D}more »« less

Is the Universal String Axion the QCD Axion

Journal Article Gaillard, Mary; Kain, Ben - Nuclear Physics B

We consider the class of effective supergravity theories from the weakly coupled heterotic string in which local supersymmetry is broken by gaugino condensation in a hidden sector, with dilaton stabilization achieved through corrections to the classical dilaton Kahler potential. If there is a single hidden condensing (simple) gauge group, the axion is massless (up to contributions from higher dimension operators) above the QCD condensation scale. We show how the standard relation between the axion mass and its Planck scale coupling constant is modified in this class of models due to a contribution to the axion-gluon coupling that appears below themore »« less

The pMSSM10 after LHC run 1

Journal Article de Vries, K.; Bagnaschi, E.; Buchmueller, O.; ... - European Physical Journal. C, Particles and Fields

We present a frequentist analysis of the parameter space of the pMSSM10, in which the following ten soft SUSY-breaking parameters are specified independently at the mean scalar top mass scale M_SUSY ≡ √m_{$$\tilde{t}$$₁}m_{$$\tilde{t}$$₂} : the gaugino masses M_1,2,3 , the first-and second-generation squark masses m_{$$\tilde{q}$$₁} = m_{$$\tilde{q}$$₂} , the third-generation squark mass m_{$$\tilde{q}$$₃}, a common slepton mass m_{$$\tilde{ℓ}$$} and a common trilinear mixing parameter A , as well as the Higgs mixing parameter μ , the pseudoscalar Higgs mass M_A and tanβ , the ratio of the two Higgs vacuum expectation values. We use the MultiNest sampling algorithm with ~more »« less

Gluino mass from dynamical supersymmetry breaking

Journal Article Dobrescu, B - Physical Review, D

We present a new mechanism for gluino mass generation in models of dynamical supersymmetry breaking. The mechanism requires two colored chiral superfields which feel a non-Abelian gauge interaction such that a fermion condensate is formed at a scale of order 1 TeV. Renormalizable hidden sector models, which typically yield unacceptably light gauginos, become viable if a gauge singlet is coupled to these chiral superfields. Moreover, the interactions of the gauge singlet with the Higgs superfields substitute the {mu} term. Visible sector models can also incorporate this mechanism; however, the models of dynamical supersymmetry breaking previously analyzed cannot be fitted inmore »« less
