The Standard Model explains how the basic building blocks of matter interact, governed by four fundamental forces. The theories and discoveries of thousands of physicists since the s have resulted in a remarkable insight into the fundamental structure of matter: everything in the universe is found to be made from a few basic building blocks called fundamental particles, governed by four fundamental forces. Our best understanding of how these particles and three of the forces are related to each other is encapsulated in the Standard Model of particle physics. Developed in the early s, it has successfully explained almost all experimental results and precisely predicted a wide variety of phenomena. Over time and through many experiments, the Standard Model has become established as a well-tested physics theory. All matter around us is made of elementary particles, the building blocks of matter. These particles occur in two basic types called quarks and leptons.

In the literal sense, nothing is simpler than an elementary particle: By definition, a particle is considered to be elementary only if there is no evidence that it is made up of smaller constituents. Yet, identifying the elementary particles, understanding their properties, and studying their interactions are turning out to be the key to illuminating why that most unelementary entity—the entire universe—is the way it is, how it came to be this way, and what its ultimate fate will be. Philosophers through history have speculated on what matter is composed of. About a hundred years ago, atoms were considered elementary, until physicists learned that atoms consisted of electrons orbiting a nucleus. We now know that quarks make up the protons and neutrons inside the nucleus.

Elementary particle physics is the study of fundamental particles and their interactions in nature. Those who study elementary particle physics—the particle physicists—differ from other physicists in the scale of the systems that they study. A particle physicist is not content to study the microscopic world of cells, molecules, atoms, or even atomic nuclei. They are interested in physical processes that occur at scales even smaller than atomic nuclei. At the same time, they engage the most profound mysteries in nature: How did the universe begin?
It seems that you're in Germany. We have a dedicated site for Germany. The book provides theoretical and phenomenological insights on the structure of matter, presenting concepts and features of elementary particle physics and fundamental aspects of nuclear physics.
This book aims to provide the basis of theoretical foundation and phenomenological knowledge of the structure of matter at the subatomic level. It starts by presenting the general concepts at the simplest level and does not require previous knowledge of the field, except for the basic quantum mechanics. The readers are gradually introduced to the increasingly more advanced topics, so that this text can accompany students all the way to their graduate and doctoral studies in experimental high-energy physics.
In physics , the fundamental interactions , also known as fundamental forces , are the interactions that do not appear to be reducible to more basic interactions. There are four fundamental interactions known to exist: the gravitational and electromagnetic interactions, which produce significant long-range forces whose effects can be seen directly in everyday life, and the strong and weak interactions , which produce forces at minuscule, subatomic distances and govern nuclear interactions. Some scientists hypothesize that a fifth force might exist, but these hypotheses remain speculative.
The Standard Model of particle physics is the theory describing three of the four known fundamental forces the electromagnetic , weak , and strong interactions, and not including the gravitational force in the universe , as well as classifying all known elementary particles. It was developed in stages throughout the latter half of the 20th century, through the work of many scientists around the world,  with the current formulation being finalized in the mids upon experimental confirmation of the existence of quarks. Since then, confirmation of the top quark , the tau neutrino , and the Higgs boson have added further credence to the Standard Model. In addition, the Standard Model has predicted various properties of weak neutral currents and the W and Z bosons with great accuracy. Although the Standard Model is believed to be theoretically self-consistent  and has demonstrated huge successes in providing experimental predictions , it leaves some phenomena unexplained and falls short of being a complete theory of fundamental interactions. It does not fully explain baryon asymmetry , incorporate the full theory of gravitation  as described by general relativity , or account for the accelerating expansion of the Universe as possibly described by dark energy. The model does not contain any viable dark matter particle that possesses all of the required properties deduced from observational cosmology.
Она проехала по Кэнин-роуд еще сотню метров и въехала на стоянку С, предназначенную для сотрудников. Невероятно, - подумала она, - двадцать шесть тысяч служащих, двадцатимиллиардный бюджет - и они не могут обойтись без меня в уик-энд. Она поставила машину на зарезервированное за ней место и выключила двигатель. Миновав похожую на сад террасу и войдя в главное здание, она прошла проверку еще на двух внутренних контрольных пунктах и наконец оказалась в туннеле без окон, который вел в новое крыло. Вскоре путь ей преградила кабина голосового сканирования, табличка на которой гласила: АГЕНТСТВО НАЦИОНАЛЬНОЙ БЕЗОПАСНОСТИ (АНБ) ОТДЕЛЕНИЕ КРИПТОГРАФИИ ТОЛЬКО ДЛЯ СОТРУДНИКОВ С ДОПУСКОМ Вооруженный охранник поднял голову: - Добрый день, мисс Флетчер. - Привет, Джон.

Соши смотрела на монитор и читала вслух: - В бомбе, сброшенной на Нагасаки, использовался не плутоний, а искусственно произведенный, обогащенный нейтронами изотоп урана с атомным весом 238. - Черт возьми! - выругался Бринкерхофф. - В обеих бомбах уран. Элементы, ответственные за Хиросиму и Нагасаки, - оба являются ураном. Никакого различия.
