The Large Hadron Collider (LHC) is the world's largest and most powerful particle collider, most complex experimental facility ever built, and the largest single machine in the world.
It was built by the European Organization for Nuclear Research (CERN) between 1998 and 2008 in collaboration with over 10,000 scientists and engineers from over 100 countries, as well as hundreds of universities and laboratories.
The Higgs boson is an elementary particle in the Standard Model of particle physics. It is the quantum excitation of the Higgs field, a fundamental field of crucial importance to particle physics theory first suspected to exist in the 1960s and was discovered in 2012 in lhc.
Inside the accelerator, two high-energy particle beams travel at close to the speed of light before they are made to collide. The beams travel in opposite directions in separate beam pipes – two tubes kept at ultrahigh vacuum. They are guided around the accelerator ring by a strong magnetic field maintained by superconducting electromagnets.
The God Particle or God particle may refer to: Higgs boson, a particle in physics sometimes referred to as the God's Particle.

Intriguing Neutrinos: The Deep Secrets of Nature’s Ghosts by Dr Elisabeth Falkonthewight
Lisa Falk's presentation about the Neutrino, one of the fundamental particles which make up the universe - Also, currently, one of the least understood.
Subatomic particles produced by the decay of radioactive elements. They're special for many reasons - They have no charge, are incredibly light, travel at near light speed and travel through most other matter.
Following the introduction to what they are, she detailed the challenges of detecting them (she's been directly involved in these experiments, including time at CERN), and the vast equipment that's used.
Finally she talked about the DUNE project, the next stage in Neutrino detection.
Presented to Cafe Scientifique, Isle of Wight, 11th May 2015.
Quantum Physics is already a very interesting subject, and so even though the presentation has all the required information to get yourself a hold on the subject, I would highly recommend everyone to do some extensive research. Well actually, there is no need for anyone to point out on the research part, you will automatically find yourselves filling the search history with some deep quantum-ish.
In these slides, I covered the following topics with PYQ's of CH-12 (Atom) of class 12th Physics:
-Alpha-particle scattering experiment
-Rutherford's model of the atom
-Bohr model,
-Energy levels,
-Hydrogen spectrum
Slides for a talk given at Physics Day at Space Center Houston, May 1-2 2014. Explains why nothing can move faster than the speed of light using spacetime diagrams.

Introduction
Discovery of Sub-atomic Particles
Atomic Models
Developments leading to Bohr’s Model of atom
Bohr’s Model for Hydrogen atom
Quantum Mechanical Model of the atoms
2. Particle Physics Aim: To determine what matter is made of, particle physics searches for elementary particles, particles that can not be broken down any further.
3. Particle Colliders To deduce the finer structure of matter, particles are smashed together. Types of particle accelerators Linear colliders Cyclotrons Synchrotrons
4. Linear Accelerators Use electric fields to accelerate charged particles. eg Crooke’s tube An early linac
9. Linear Accelerators A progressive linac. The voltage switches from + to – progressively attracting and repelling the charged particle. The chamber is evacuated.
10. Linear Accelerators Stanford Linear Accelerator Center (SLAC) is the largest linac, 3.2 kilometers long and accelerates electrons to 25 GeV.
11. Cyclotron A circular particle accelerator. It uses magnetic fields to turn charged particles in a circular path. How does this work?
12. The motion of charged particles in magnetic fields Magnetic fields are drawn like an arrow When the arrow travels away, it looks like this X When the arrow comes towards you it looks like a point.
19. Synchrotrons EgFermilab circumference= 6.3km CERN c=27km turn the charged particles with magnetic fields vary the magnetic field to ensure the radius is fixed. This way the charged particle goes round and round the same “race track” and can be accelerated to VERY high speeds, 99.99% the speed of light!
25. Formative Practical InvestigationParticle Collider Simulator Aim: Determine what shape and size the object is inside the detector. How fast will you make the incoming particle? Will you vary the speed? What will be the direction of your incoming particle? How will you be systematic in your approach? How will you record your results?
26. Particle Detectors How can we see the unseeable? Cloud chambers – use super saturated vapour. Charged particles cause the vapour to condsense into a liquid. Bubble chambers – use super heated liquid. Charged particles cause the liquid to start boiling.
27. Particle Detectors Only charged particles leave tracks. Magnetic fields turn particles according to their charge. Scientist can work out the charge, mass and speed of the particles.
28.
29. Discovery of the omega minus particle Predicted 1962, found 1964.
31. Particle Physics >1950’s So instead of finding elementary particles in particle detectors, a whole “zoo” of particles were discovered. !
32. Baryons are subatomic particles. The Greek word 'barys' means 'heavy'. This is a list of baryons known to date. Proton, Neutron, Delta, Lambda, Charmed lambda, Bottom lambda, Sigma, Xi, Charmed Xi, Omega, Charmed Omega
33. Mesons (from the greek “middle”) such as pions, kaons, eta-mesons. Some particles existed for very very short periods of time. Scientist found it hard to make sense of the bewildering array of new particles.
36. Particle Physics >1950’s So instead of finding elementary particles in particle detectors, a whole “zoo” of particles were discovered.
37. Murray Gell Mann Gell Mann tried to make sense out of this array of particles in a similar way that Mendeleev made sense out of the elements. He realised there were patterns in their properties.
38. Murray Gell Mann He proposed the existence of quarks, elementary particles that combine to form many different particles (1964) There are six ‘flavours’ of quarks!
43. There are force particles called gluons which glue protons (or neutrons) together. u u d
44. Current theory of matter Particles we call ordinary matter (has mass, occupies space) is composed of elementary fermions, namely quarks and leptons. Leptons Matter Fermions Quarks
45.
46. Neutrinos an elementary particle travels close to the speed of light electrically neutral can pass through matter almost undisturbed. extremely difficult to detect. Neutrinos have a very small, but nonzero mass.
47.
48. Hadrons - matter made of quarks Baryons are made of three quarks Mesons are made of one quark and one antiquark
52. (don’t write) 2nd generation are just heavier versions of the 1st generation particles.
53. (don’t write) 3rd generation even heavier still. Tau, tau neutrino – 1974~1977 Bottom – 1977 Top quark -1992
54. If there are so many types of hadrons, mesons and leptons why don’t we see them every day?? Why is most of the matter we experience only protons, neutrons and electrons?
55. Stability and Energy This triangle can be in the following configurations – Energy of A > Energy of B > Energy of C A B C
56. Stability and Energy Triangle A would quickly “decay” into a lower energy state, C as it is completely unstable. A C
57. Stability and Energy Even B would eventually decay in C with a tiny input of energy. It is not very stable. B C
58. Stability and Energy As the object moves into a lower energy state some energy is released. B C
59. Stability and Energy It would require an input of energy to move the object into a higher energy state B C
60. Many things behave in a similar way. Eg Electrons in energy levels Electrons can jump up to higher energy levels with the input of energy. The electrons then fall back down to a lower, more stable energy configuration, releasing energy in the form of electromagnetic radiation (light)
61. Unstable elements are said to be radioactive. They decay to more stable elements with the release of energy. The newly formed elements have less energy and are more stable. Unstable fermions decay into stable fermions. Egtaumuonelectron
62.
63. The most stable particles compose most matter you see – the electron (neutrino) has the lowest energy of any lepton The proton (uud) is the lowest energy state of any hadron. The neutron is less stable (ddu)and has a half life of 10 minutes when not in a nucleus!
