The Standard Model of particle physics is the theory describing three of the four known fundamental forces (electromagnetic, weak and strong interactions – excluding gravity) in the universe and classifying all known elementary particles.
This article describes the mathematics of the Standard Model of particle physics, a gauge quantum field theory containing the internal symmetries of the unitary product group SU(3) × SU(2) × U(1). The theory is commonly viewed as describing the fundamental set of particles – the leptons , quarks , gauge bosons and the Higgs boson .
Secondary School Certificate (SSC), Secondary School Leaving Certificate (SSLC) or Matriculation examination, is a public examination in Bangladesh, India, Pakistan, Nepal and Maldives conducted by educational boards for the successful completion of the secondary education exam in these countries. Students of 10th grade/class ten can appear in ...
All India Secondary School Examination, commonly known as the class 10th board exam, is a centralized public examination that students in schools affiliated with the Central Board of Secondary Education, primarily in India but also in other Indian-patterned schools affiliated to the CBSE across the world, taken at the end of class 10.
The results of the examinations are usually declared in the first week of May to Mid-June. In general, about 80% of candidates receive a passing score. [8] The Delhi High Court has directed the Central Board of Secondary Education and Delhi University to discuss the ways by which the results of the main exam, revaluation, and compartment exam can be declared earlier than usual so that ...
Most important task of the board, among few others, is to conduct the SSC for 10th class and HSC for 12th class examinations. [2] It is the most popular education board in terms of enrollment in high school in India only after the Central Board of Secondary Education.
Paper 1 – multiple choice questions on the SSC (20%) Paper 2 – free response questions on the SSC (32% at SL, 36% at HL) Paper 3 – free response questions on the options (24% at SL, 20% at HL) At the Standard Level, the examinations are respectively 45 minutes, 1 hour and 15 minutes, and 1 hour long.
The search for the Higgs boson was a 40-year effort by physicists to prove the existence or non-existence of the Higgs boson, first theorised in the 1960s.The Higgs boson was the last unobserved fundamental particle in the Standard Model of particle physics, and its discovery was described as being the "ultimate verification" of the Standard Model.
