It is very easy to customize plugins according to the needs of a particular business. I thought about what would happen by placing a text widget in the sidebar beneath my banner ad, and so it went. If you are using videos on your site then this is the plugin to use. Also our developers are well convergent with the latest technologies and bitty-gritty of wordpress website design and promises to deliver you the best solution that you can ever have. <br><br>Generally, for my private income-making market websites, I will thoroughly research and discover the leading 10 most worthwhile niches to venture into. You will have to invest some money into tuning up your own blog but, if done wisely, your investment will pay off in the long run. It sorts the results of a search according to category, tags and comments. So if you want to create blogs or have a website for your business or for personal reasons, you can take advantage of free Word - Press installation to get started. Word - Press makes it possible to successfully and manage your website. <br><br>Here are a few reasons as to why people prefer Word - Press over other software's.

	In particular ~~the hadronic components of the physical photon consist of the lightest vector mesons <math>\rho, \omega</math> and <math>\phi</math>~~. ~~Therefore, interactions between photons and hadronic matter occur~~ by ~~the exchange of~~ a ~~hadron between~~ the ~~dressed photon~~ and ~~the hadronic target~~.

	~~==Background==~~
	~~Measurements of the interaction between energetic photons and hadrons show that the interaction~~ is ~~much more intense than expected by~~ the ~~interaction of merely photons~~ with the ~~hadron's electric charge. Furthermore, the interaction~~ of ~~energetic photons with protons is similar~~ to the ~~interaction of photons with neutrons~~<~~ref~~>~~Bauer~~, ~~T. H.~~, ~~Spital, R. D., Yennie, D. R.~~ and ~~Pipkin, F. M, The hadronic properties of~~ the ~~photon in high-energy interactions, Rev~~. ~~Mod. Phys. 50~~, ~~261–436 (1978)~~, ~~pages 292-293</ref>~~ in ~~spite of~~ the ~~fact that~~ the ~~electric charge structures~~ of ~~protons~~ and ~~neutrons are substantially different~~.

	~~According~~ to ~~VMD~~, ~~the photon is a superposition~~ of ~~the pure electromagnetic photon (which interacts only with electric charges) and vector meson~~.

	~~Just after 1970, when more accurate data on the above processes became available, some discrepancies with the VMD predictions appeared~~ and ~~new extensions of the model were published~~.<~~ref>Generalized vector dominance and inelastic electron nucleon scattering—the small <math>\omega</math~~>~~′ region, Sakurai J. J. and Schildknecht D., Phys. Lett., 40B (1972) 121~~<~~/ref~~> ~~These theories~~ are ~~known~~ as ~~Generalized Vector Meson Dominance theories (GVMD)~~.

	~~==VMD and Hidden Local Symmetry==~~
	~~Whilst the ultraviolet description~~ of ~~the standard model~~ is ~~based on QCD, work over many decades has involved writing a low energy effective description of QCD,~~ and ~~further, positing a possible ``dual`` description. One such popular description is~~ that of the ~~hidden local symmetry~~.~~<ref>Nonlinear Realization and Hidden Local Symmetries, Bando, Masako and Kugo, Taichiro and Yamawaki, Koichi, DOI~~: 10.~~1016~~/~~0370-1573(88)90019-1</ref> The dual description is based on~~ the ~~idea~~ of ~~emergence of gauge symmetries~~ in ~~the infrared of strongly coupled theories~~. ~~Gauge symmetries are not really physical symmetries (only the global elements of~~ the ~~local gauge group are physical)~~. ~~This emergent property of gauge symmetries was demonstrated~~ in ~~Seiberg duality~~ <~~ref~~>~~Electric - magnetic duality in supersymmetric nonAbelian gauge theories , Seiberg, N., hep-th/9411149~~<~~/ref~~> ~~and later~~ in the ~~development of~~ the ~~AdS/CFT correspondence~~.~~<ref>The Large N limit~~ of ~~superconformal field theories~~ and
	~~supergravity~~, ~~Maldacena, Juan Martin~~, ~~hep~~-~~th/9711200</ref> In its generalised form, Vector Meson Dominance appears~~ in ~~AdS/CFT, AdS/QCD , AdS/condensed matter and some Seiberg dual constructions~~. It ~~is therefore a common place idea within the theoretical physics community~~.

	~~==Attacks on VMD==~~
	~~Measurements of the photon~~-~~hadron interactions in higher energy levels show that VMD cannot predict the interaction in such levels. In his Nobel lecture<ref>[[Jerome Isaac Friedman\|J.I. Friedman]]~~, ~~Nobel Lecture~~, ~~Deep Inelastic Scattering~~, ~~Comparisons with the Quark Model, Rev~~. ~~Mod. Phys. vol 63 3 1991~~<~~/ref~~> ~~[[Jerome Isaac Friedman\|J.I. Friedman]] summarizes~~ the ~~situation of VMD as follows:~~
	~~"...this eliminated~~ the ~~model [VMD] as a possible description of deep inelastic scattering... calculations of the generalized vector-dominance failed in general~~ to ~~describe the data over~~ the ~~full kinematic range~~.~~.."~~

	~~The theoretical basis of VMD raised doubts~~ as ~~well~~. ~~According to VMD a photon~~ is ~~a superposition of pure electromagnetic photon which always moves in~~ the ~~speed~~ of ~~light and hadronic matter which always moves in lower speed~~. ~~Therefore~~ the ~~VMD idea seems to contradict [[Special Relativity]].<ref>[[Eliyahu Comay\|E~~. ~~Comay]] Remarks on Photon-Hadron Interactions~~, ~~Apeiron vol. 10, 87 (2003)</ref>~~

	~~Today, VMD is not considered as part of~~ the ~~[[Standard Model]].<ref>H.B. O’Connell, B.C. Pearce, A.W. Thomas~~ and ~~A.G. Williams, Rho~~-~~omega mixing, vector meson dominance and~~ the ~~pion form~~-~~factor~~, ~~Prog. Nucl. Part. Phys. 39 (1997) 201~~-~~252</ref>~~
