"I'm not going to lay back and watch somebody die": a qualitative study of how people who use drugs' naloxone experiences are shaped by rural risk environment and overdose education/naloxone distribution intervention.

Background: Overdoses have surged in rural areas in the U.S. and globally for years, but harm reduction interventions have lagged.

Lepton flavor violation in B decays?

The LHCb Collaboration's measurement of R_{K}=B(B^{+}→K^{+}μ^{+}μ^{-})/B(B^{+}→K^{+}e^{+}e^{-}) lies 2.6σ below the Standard Model prediction. Several groups suggest this deficit to result from new lepton nonuniversal interactions of muons.

Technicolor explanation for the CDF Wjj excess.

We propose that the 3.2σ excess at ~150 GeV in the dijet mass spectrum of W+jets reported by CDF is the technipion πT of low-scale technicolor. Its relatively large cross section is due to production of a narrow Wjj resonance, the technirho, which decays to WπT.

B-meson gateways to missing charmonium levels.

We outline a coherent strategy for exploring the four remaining narrow charmonium states [eta(')(c)(2(1)S0), h(c)(1(1)P1), eta(c2)(1(1)D2), and psi(2)(1(3)D2)] expected to lie below charm threshold. Produced in B-meson decays, these levels should be identifiable now via striking radiative transitions among charmonium levels and in exclusive final states of kaons and pions. Their production and decay rates will provide much needed new tests for theoretical descriptions of heavy quarkonia.
