know any good introduction books to tensors?

i really want to start learning them but i dont know if they teach us tensors in 3rd or 4th yr and i dont wan to wait till 4th year lol

thanks

A good text is the Schaum's version. It has lots of examples.

That link didn't work for me, but this one does.

thankyou

now to revise advanced vector calculus for my jan exam

Guess what I found. Someone explores the implications of this putative discovery. [1112.3017] Implications of a 125 GeV Higgs scalar for LHC SUSY and neutralino dark matter searches
Howard Baer, Vernon Barger, Azar Mustafayev
(Submitted on 13 Dec 2011)

They analyzed it in two subsets of the Minimal Supersymmetric Standard Model:

mSUGRA: free parameters m0, m1/2, A0, tan(beta), sign(mu)
and
NUHM2: free parameters m0, m1/2, A0, tan(beta), mu, mA

m0 = mass scale of the spin-0 superpartners of the elementary fermions
m1/2 = mass scale of the spin-1/2 superpartners of the gauge particles
mA = mass scale of the heavy Higgs particles predicted by the MSSM

For both mSUGRA and NUHM2, m0 >~ 0.8 TeV, pushing the squark and slepton masses into the multi-TeV range. Those particles may thus be difficult to make with the LHC.

However, m1/2 is less constrained, meaning that the LHC may be able to make gluinos, neutralinos, and charginos more easily.

Both mSUGRA and NUHM2 tend to produce too much neutralino dark matter, except if the lightest neutralino is higgsino-like, with a mass around 0.8 TeV. However, that would bump the bino, wino, and gluino masses into the TeV range. Especially the gluinos, which are otherwise the easiest for the LHC to make.

Neutralinos = mixtures of the bino, neutral wino, and neutral Higgsinos
Charginos = mixtures of the charged wino and charged Higgsino
The lightest supersymmetric particle is usually expected to be a neutralino.

So this putative discovery may mean that it'll be awfully hard for the LHC to detect supersymmetric particles.

Can we please have someone explain this in english?

lpetrich's last sentence is the important one.

If/when the LHC discovers the Higgs particle, it will be a good thing and worth a Nobel prize.

If, however, the LHC were to discover the existence of supersymmetry, a revolution, almost on the scale of the discovery of quantum mechanics, could be said to have occurred.

The conclusion of the paper is that, given the mass of the Higgs, any supersymmetric particles have masses such that it's going to be damn hard for the LHC to see them. So we still won't know about supersymmetry ...... sad face...
