[^1]: A new spin-0 singlet with pseudoscalar couplings to Dark Matter can mix with the SM Higgs, which will lead to spin-0 mass eigenstates which are not CP eigenstates. Such a scenario does not require new states beyond the mediator and dark matter, but is strongly constrained by Higgs coupling measurements [@Baek:2017vzd].
[^2]: For simplified models in which the Higgs mixes with scalar mediators that couple to dark matter, measurements of Higgs couplings provide a stronger bound on the mixing angle than any mono-X search [@Bell:2016ekl].
[^3]: The contribution from the exchange of the heavy scalar $H$ to the Dark Matter-nucleus cross section is weaker by a factor $M_h^4/M_H^4$ and further suppressed by $g_{H_\chi}$, which vanishes at $\tan\beta=1$ and $\cos(\beta-\alpha)=0$.
<|endoftext|>Here’s one way to bolster a business, and pick up some talented staffers in a tight hiring market.
Seattle supercomputer maker Cray announced Thursday that it has hired the majority of employees from Austin, Texas-based SystemFabricWorks, a company that’s described as a leader in “storage interconnect solutions and software.”
Joining Cray as part of the deal are former SystemFabricWorks CEO Bob Pearson; former vice president of business development Bill Boas; and a number of engineers who will add expertise to Cray’s Lustre-based storage solutions.
Interestingly, even with the defections, SystemFabric
