Effects of TeV Scale Gravity on e+e− → W+W−
نویسنده
چکیده
We study the process e+e− → W+W− to probe low-scale gravity at high energy linear colliders. A characteristic signature of extra-dimensions models is the forward-backward asymmetry due to the interference of spin2 graviton and spin-1 SM gauge boson exchange terms, even when rightpolarised electron beam is used. Our analysis shows that larger than 5% asymmetry is possible at a linear collider with √ s = 500 (800) GeV if the mass scale, MS is smaller than 2.7 (4.5) TeV. W − polarisation factors measured with a few percent accuracy will also be able to put similar limits on MS .

Effects of feeding Artemia franciscana enriched with HUFA, vitamins C and E on growth performance, survival and stress resistance of cuttlefish (Sepia pharaonis) (Ehrenberg, 1831)
This study aimed to evaluate the effects of using Artemia franciscana enriched with cod liver oil and vitamins C and E on the growth, survival and stress resistance of juvenile Sepia pharaonis (Pharaoh cuttlefish). Twenty-five days after hatching, the larvae of S. pharaonis were transferred into culture tanks with an average length of 15.97±0.15 mm and average body weight of 3.53±0.03 g, in ele...
متن کاملEikonal contributions to ultra high energy neutrino-nucleon cross sections in low scale gravity models
We calculate low scale gravity effects on the cross section for neutrino-nucleon scattering at center of mass energies up to the Greisen-Zatsepin-Kuzmin (GZK) scale, in the eikonal approximation. We compare the cases of an infinitely thin brane embedded in n = 5 compactified extra-dimensions, and of a brane with a physical tension MS = 1 TeV and MS = 10 TeV. The extra dimensional Planck scale M...
متن کاملPalaeostress configuration of Pan-African orogeny: evidence from the Igarra schist belt, SW Nigeria
The stress configuration and tectonic analysis of the Pan – African orogeny is drawn from the Igarra schist belt, southwestern Nigeria. The analysis of conjugate shear fractures of the schist belt indicates that two distinct compressive events (NE – SW and E – W) occurred in this Pan – African mobile zone. The palaeostress systems reveal a clockwise rotation of compressional axis from D1 (NE – ...

The purpose of this study was to evaluate the probable effects of the vitamin E addition in different levels to the extender of chicken semen on spermatozoa quality during storage of semen at 4°C for 0, 3, 6, 10 and 24 hours. Eight young Ross broiler breeder strain 308 roosters were used in this experiment. The collected semen from all roosters was mixed together and diluted with modified a Rin...
متن کاملThe $w$-FF property in trivial extensions
Let $D$ be an integral domain with quotient field $K$, $E$ be a $K$-vector space, $R = D propto E$ be the trivial extension of $D$ by $E$, and $w$ be the so-called $w$-operation. In this paper, we show that $R$ is a $w$-FF ring if and only if $D$ is a $w$-FF domain; and in this case, each $w$-flat $w$-ideal of $R$ is $w$-invertible.
