XXI DAE-BRNS High Energy Physics Symposium

These proceedings gather invited and contributed talks presented at the XXI DAE-BRNS High Energy Physics Symposium, which was held at the Indian Institute of Technology Guwahati in December 2014. The contributions covermany of themost active research areas in particle physics, namely (i) Electroweak Physics; (ii) QCD andHeavy Ion Physics; (iii) Heavy Flavour Physics and CP Violation; (iv) Neutrino Physics; (v)Astro-particle Physics and Cosmology; (vi) Formal Theory; (vii) Future Colliders and NewMachines; and (viii) BSM Physics: SUSY, Extra Dimensions, Composites etc. The DAE-BRNS High Energy Physics Symposium,widely considered to be one of thepremiere symposiums organised in India in the field of elementary particle physics,is held everyother year and supported by the Board of Research in Nuclear Sciences,Department of Atomic Energy, India.Roughly 250 physicists and researchers participated in the 21st Symposium, discussing the latest advancements in the field in 18 plenary review talks, 15 invited mini-review talks and approximately130 contributed presentations. Bringing together the essential content, the book offers a valuable resource for both beginning and advanced researchers in the field.
