![]() But we found exactly one company that rents pre-transformed vans. Our summer budget definitely did not allow us to purchase a minivan or Sprinter. Encompassing everything from the family minivan to cannibalized hotel shuttles to gorgeous Sprinter vans, these are not your parents’ VW bus (or, for that matter, my parents’ VW bus, which once in 1982 left us stranded on the side of the road in very rural eastern Oregon while my dad hiked like Lawrence of Arabia toward the shimmer of a faraway farmhouse). In good old CO, trailheads, climbing areas and campgrounds bristle with tricked out DIY camper vans: half dirtbag, half steampunk, and all awesome. Living just outside Boulder, Colorado, we knew an alternative. And we did not want our mellow to be harshed. In short, we worried that an RV would harsh our mellow. An RV equipped with a flat screen TV and all the amenities of home worked against this purpose. and Canada without it being filtered through live cams and edu-casts. And an RV didn’t quite fit our vibe – a big part of our vacation goal was to unplug and help the offspring, 8 and 10, experience a good chunk of the western U.S. But a thorough search showed than an RV would quickly break our bank. ![]() So this summer with a carefully guarded month to spend on a hiking- and climbing-focused family road trip, my wife and I looked to split the difference between abject dirtbagging and luxurious hotel life. But the realities of family travel make it tricky to car camp on BLM land with oatmeal for breakfast, peanut butter and jelly for lunch and hotdogs for dinner.

Future measurements with larger datasets will test whether leptonic CP violation is larger than the CP violation in quarks.Ĭhristenson, J. Our results indicate CP violation in leptons and our method enables sensitive searches for matter–antimatter asymmetry in neutrino oscillations using accelerator-produced neutrino beams. The 3 σ confidence interval for δ CP, which is cyclic and repeats every 2π, is for the so-called normal mass ordering and for the inverted mass ordering. Here we report a measurement using long-baseline neutrino and antineutrino oscillations observed by the T2K experiment that shows a large increase in the neutrino oscillation probability, excluding values of δ CP that result in a large increase in the observed antineutrino oscillation probability at three standard deviations (3 σ). Until now, the value of δ CP has not been substantially constrained by neutrino oscillation experiments. This CP violation can be measured in muon neutrino to electron neutrino oscillations and the corresponding antineutrino oscillations, which are experimentally accessible using accelerator-produced beams as established by the Tokai-to-Kamioka (T2K) and NOvA experiments 10, 11. Leptonic mixing, which appears in the standard model’s charged current interactions 5, 6, provides a potential source of CP violation through a complex phase δ CP, which is required by some theoretical models of leptogenesis 7, 8, 9. It has been shown that CP violation in leptons could generate the matter–antimatter disparity through a process called leptogenesis 4. So far, CP violation has not been observed in non-quark elementary particle systems. However, CP violation in quarks is too small to support this explanation. Sakharov proposed 3 that CP violation is necessary to explain the observed imbalance of matter and antimatter abundance in the Universe. ![]() Violation of this CP symmetry was first observed in 1964 1, and CP violation in the weak interactions of quarks was soon established 2. The charge-conjugation and parity-reversal (CP) symmetry of fundamental particles is a symmetry between matter and antimatter.
