Possible strong interaction effects arising when the Higgs mass MH is sufficiently large are investigated in the system of interacting Higgs, using dispersion relations (N/D method). A simple model indicates that for MH≳1 TeV several such effects are present: an 1=0 bound state, large s-wave phase shifts and a resonance-like state. In the range 1.5≲MH≲3.5 TeV the above bound state amounts to an approximate bootstrap (self-consistent) solution for the Higgs with respect to both its mass and coupling. Other aspects of the H-H strong interaction system are also investigated.

The system of interacting Higgs and longitudinal gauge bosons, when the Higgs mass MH varies above 1 TeV, is studied using dispersion relations (N/D method). Models satisfying unitarity and analyticity constraints are constructed and solved exactly. For MH≲0.6 TeV the dispersive and perturbative (tree level) amplitudes are similar. For MH≳1.5 TeV , however, they much differ in structure. For MH≃1.5, in ZZ→ZZ the dispersive amplitudes exceed the perturbative ones by factors 2~4. There are indications of strong interaction effects: In HH→HH there is an ℓ=0 bound state, which can be taken as the Higgs itself; in fact, for MH≃2.5 there is an almost self-consistent solution with respect to the mass, and very roughly with respect to the coupling. There is also some indication of a resonance in ZZ→ZZ, as well as in HH→HH.

Abstract Persistent stress of external or internal origin accelerates aging, increases risk of aging related health disorders, and shortens lifespan. Stressors activate stress response genes, and their products collectively influence traits. The variability of stressors and responses to them contribute to trait heterogeneity, which may cause the failure of clinical trials for drug candidates. The objectives of this paper are: to address the heterogeneity issue; to evaluate collective interaction effects of genetic factors on Alzheimer’s disease (AD) and longevity using HRS data; to identify differences and similarities in patterns of genetic interactions within two genders; and to compare AD related genetic interaction patterns in HRS and LOADFS data. To reach these objectives we: selected candidate genes from stress related pathways affecting AD/longevity; implemented logistic regression model with interaction term to evaluate effects of SNP-pairs on these traits for males and females; constructed the novel interaction polygenic risk scores for SNPs, which showed strong interaction potential, and evaluated effects of these scores on AD/longevity; and compared patterns of genetic interactions within the two genders and within two datasets. We found there were many genes involved in highly significant interactions that were the same and that were different within the two genders. The effects of interaction polygenic risk scores on AD were strong and highly statistically significant. These conclusions were confirmed in analyses of interaction effects on longevity trait using HRS data. Comparison of HRS to LOADFS data showed that many genes had strong interaction effects on AD in both data sets.

The exact solutions of the one-dimensional Klein–Gordon equation for the Rosen–Morse type potential with equal scalar and vector potentials are presented. First, we briefly review Nikiforov–Uvarov mathematical method. Using this method, wave functions and corresponding exact energy equation are obtained for the s-wave bound state. It has been shown that the results for Rosen–Morse type potentials reduce to the standard Rosen–Morse well and Eckart potentials in the special case. The PT-symmetry for these potentials is also considered.
