To me the 3rd avenue is the most promising. But also the hardest and riskiest to pursue for any individual in his prime years. I'd love it if someone broke through. Maybe I'd even read about it here at first ;)Psychedelic fathomernoreply@blogger.comtag:blogger.com,1999:blog-2846514233477399562.post-56089938074113412672018-05-17T21:42:31.330+01:002018-05-17T21:42:31.330+01:00I meant the next generation experiments should be ...I meant the next generation experiments should be sensitive to that scale. The P2 experiment in Mainz is expected to reduce the error on QW by a factor of five.

But this value has the same magnitude as the current experimental uncertainty of the proton weak charge, placed at (delta) QW = 0.0045.<br /><br />Is there sufficient resolution here to make claims about BSM physics at 100 TeV?Ervin Goldfainhttps://www.blogger.com/profile/07585008304556273617noreply@blogger.comtag:blogger.com,1999:blog-2846514233477399562.post-52808024606796345842018-05-16T23:33:30.777+01:002018-05-16T23:33:30.777+01:00"numerical accidents making the Z boson effec..."numerical accidents making the Z boson effectively protophobic"<br /><br />I'm excited, I just love low-energy numerical accidents and this is new to me. (For another numerical accident connecting Z boson with the strong force, see <a href="http://arxiv.org/abs/hep-ph/0507144" rel="nofollow">here</a>.) The accident here is that 1 - 4 sin^2 theta_w is small.Mitchellhttps://www.blogger.com/profile/10768655514143252049noreply@blogger.com
