Anomaly Definition and 114 Threads

I am working a problem from the Mohapatra textbook unification and supersymmetry and the question is to show that if any rep of a grp is pseudo real then it is automatically anomaly free. There is not much in the chapter (2) on how to go about this. All I know is that for a pseudo real...

Beginners question : In GUTS what is the relevance of anomaly cancellation. Is it in some sense an axiom - like we say we must have local invariance - or is it in just some mathematical requirement? Thanks in advance.

The electromagnetic neutral pion decay is a three-point interaction: it decays into two virtual and charged Kaons or Protons, of which one then radiates a photon and then annihalates with the other to produce a second photon. (Obviously, a neutral particle cannot radiate photons directly)...

Base 10 Anomaly An applied 49-year study into the origin of pi and the Base 10 number system resulted in the finding of a highly anomalous formula. Essentially, the finding derives from the perfect ratios (0:1:1:2:3:4) given by Pythagoras who we know studied and perhaps taught in the...

http://lanl.arxiv.org/pdf/quant-ph/0501041 the pioneer anomaly is due to topological phase defect of light

Is there something wrong with this reasoning: First the question: "A rocket A leave Earth at a speed v at a time where the clocks onboard and those on Earth read 0. After a time T (for the Earth's clock), a second rocket is lauched with a speed u > v. The second rocket catches up with the...

Is the pioneer anomaly due to quintessence? I thought this was interesting http://www.arxiv.org/PS_cache/gr-qc/pdf/0407/0407023.pdf

In his book The Ascent of Science, Brian L. Silver states "The order of increasing nuclear charge was, with one exception, identical with the order of increasing atomic weight." What is that exception, and why?

Just for fun... If a baby is born on Mars on July 12, 2014, what would his/her astrological Sun sign be?

String Theory: (TOE) Schwarz-Green Anomaly Cancellation Equasions (1984): S_o = \int d^o xe \left[- \left( \frac{1}{2 K^2} \right) R - \left( \frac{1}{K^2} \right) \left( \varphi^-2 \right) \vartheta_r \varphi \vartheta^n \varphi - \left( \frac{1}{4 g^2} \right) \right]... ... \left[...

http://arxiv.org/abs/astro-ph/0203466 We present new spectroscopic observations of an old case of anomalous redshift--NGC 7603 and its companion. The redshifts of the two galaxies which are apparently connected by a luminous filament are z=0.029 and z=0.057 respectively. We show that in the...

f(x) = (1 - x^2)^1/2 This all stems from me approximating pi by numerically evaluating the integral S f(x)dx from 0 to 1 and multiply the sum by 4. Now... Would you agree that f(x) has a derivative f'(x) = (1 - x^2)^-1/2 * -2x ? According to my textbook this is so. Now I can...
