where we have introduced a useful object

W = 1/2 Mij φi φj + 1/6 yijk φi φj φk,

14 hours of high energy theoretical physics per day = insane.

At lunch me and three other people acted out the first 5 minutes of Super Troopers and couldn't stop laughing for an hour afterward. I'm regressing quickly.

Note that yijk is totally symmetric under the interchange of the indices ijk and represents the yukawa interaction of a scalar with two fermions, while Mij is a symmetric mass matrix on fermions.

This process is usually referred to as Drell-Yan production, even though we will most likely produce neither Drell nor Yan at the LHC.

Why bother building the thing, then?

I don't find it convenient to write that at all. I couldn't begin to guess the required key combinations. :clueless:

This means that the supergravity effective Lagrangian contains non-renormalizable terms that
communicate between the two sectors and are suppressed by powers of the Planck mass MP. These
will include

LNR = (−1/MP)F(1/2)(fa λa λa + (1/6) y′ijk φi φj φk + (1/2) μ′ij φi φj)+ c.c. − (1/MP^2) FF* kij φi φj* (6.35)

where F is the auxiliary field for a chiral supermultiplet in the hidden sector, and φi and λa are the scalar and gaugino fields in the MSSM, and fa, y′ijk, and kij
are dimensionless constants. By
themselves, the terms in eq. (6.35) are not supersymmetric, but it is possible to show that they are part of a non-renormalizable supersymmetric Lagrangian

There's a fairly basic error in this.

Why would God cease to exist if he hated himself? Wouldn't that just make him like the average Englishman?

So will about 99.99999% of people (really)

I would be very surprised if more than ~6000 people have any real knowledge of supersymmetry.

Isn't it fun being on the leading edge of the distribution?

YAYYYYYY :bounce: :bounce: :bounce:

KrazyHorse

Might be more like 3000. Not sure. Figure out how many people have physics PhDs from the last 30 years (40000?), multiply by the fraction that got it in high energy theory (7%?) and then multiply by two (last factor to account for smart experimentalists as well as able people who do not get a PhD).
