The production of J=ψ mesons in jets is studied in the forward region of proton-proton collisions using data collected with the LHCb detector at a center-of-mass energy of 13 TeV. The fraction of the jet transverse momentum carried by the J=ψ meson, zðJ=ψÞ ≡ p T ðJ=ψÞ=p T ðjetÞ, is measured using jets with p T ðjetÞ > 20 GeV in the pseudorapidity range 2.5 < ηðjetÞ < 4.0. The observed zðJ=ψÞ distribution for J=ψ mesons produced in b-hadron decays is consistent with expectations. However, the results for prompt J=ψ production do not agree with predictions based on fixed-order nonrelativistic QCD. This is the first measurement of the p T fraction carried by prompt J=ψ mesons in jets at any experiment.

Activist hedge funds are the new breed of corporate raiders, yet we know little about how the management and board of target firms respond to activist investors. Using a behavioral perspective, we propose that an activist's reputation for being confrontational conveys information to the target company as to what they are likely to encounter in an activist campaign. To avoid the potential adverse consequences of engaging in such a contest, we propose and
