HB- has been inserted inside YB0 and prestressed against HB+. Concrete towers have been erected to survey mapper rails being installed inside HBs. HB+ cradle is being moved near main shaft PX56.

13 A SEMMI ÖRVÉNyÉBEN Newton: absolute space AND absolute time Mach,Leibnitz: relational to all other objects, üres térben nincs gyorsulás,tömeg Einstein: spec.rel-ben absolute space-time ált.rel –ben acceleration is relational to gravitation: spacetime is A something Before QM and Higgs: They specified the benchmark for defining accelerations Higgs Ocean = Asymmetric solution for symmetic theory Higgs-field condenses at 10**15 K (10**-11 sec) NO mass before NOW we know: WHY objects resist accelerations????

25 FERMION: 3 * 32 = 96 BOSON: Vector: g, Z, W+,W-, 8gluons = 12 Scalar: H = 1 Number of elementary particles in SM: 109 Nem sok ez egy kicsit???? Mengyelejevnek elég volt 66 elem.

26 It describes all fundamental particles of our Universe As far as we know them at present … They are controlled by UNIVERSAL laws of physics … There are (at least) 26 constants of Nature 12 masses, 3 coupling strengths, 11 mixing parameters Some of these are left – right asymmetric ! And we know that this theory is incomplete …

27 Why is the universe constructed with this range of seemingly random numbers? Why do the elementary particles have just the right properties to allow nuclear process to happen, stars to light up, planets to form around stars, and on at least one such planet, life to exist? In string theory, particle properties are determined by string vibrational patterns.

45 Fact 3) The combined strands of the superconducting cable being produced for the LHC would go around the equator 6.8 times. If you added all the filaments of the strands together they would stretch to the sun and back 5 times with enough left over for a few trips to the moon. Fact 6) The ATLAS cavern could hold the nave of Notre Dam cathedral. Fact 7) When the 27km long circular tunnel at CERN was excavated, between lake Geneva and the Jura mountain range, the two ends met up with just one centimetre of error. Fact 10) The Large Hadron Collider at CERN could be the most ambitious scientific undertaking ever. The results of LHC experiments will probably change our fundamental knowledge of the universe. Fact 16) CERN is the world's largest laboratory dedicated to the pursuit of fundamental science. Fact 21) If the Higgs boson exists the LHC will be able to make this particle detectable. Confirming or contradicting the first evidence of the Higgs particle is an exciting prospect! Fact 29) The Grid is a service for sharing computer power and data storage capability over the Internet. Its ultimate aim is to turn the global network of computers into one vast computational resource. Fact 30) Verification of the theory that explains why the sun shines – the weak force - is one of CERN’s biggest achievements. Fact 31) The discovery of the neutral current was announced at CERN in 1973. The theory was finally confirmed in 1983 with the direct observation of W and Z particles.. Fact 41) In 2003, 6.1% of traffic at Geneva International Airport was related to CERN, a total of 54 868 passengers. Understanding all of the different forces of nature within one framework is one of the ultimate goals of physics. Decades of experiments at CERN are working towards this. 99.999999999999% of an atom’s volume is empty space. If the proton were a pea, the electron would be in the back of the strands at Old Trafford. When protons arrive in the LHC they are travelling at 0.999997828 times the speed of light. Each proton goes around the 27km ring over 11 000 times a second. The proton beam of the LHC will have an energy equivalent to a person in a Subaru driving at 16 000mph.

46 Higgs a román boltiv ZÁRÓKÖVE Ha nem találjuk, akkor az SM összeomlik Alternativ megoldás: 3*4 = 12 gyufa kell 4 háromszöghöz. Hogyan lehet 6-ból 4-t csinálni??? At high enough temperatures Higgs ocean evaporates:no difference EM-Weak In LHC Higgs particles knocked out as energetic underwater collisions can knock H2O molecules out of the Atlantic.

50 Dark MATTER In order to have approximately flat universe now, some mechanism must have tuned the matter-energy density of the early universe extraordinary close to the critical density. Inflation cures the original curvature. proton-neutron matter less than 5 % Zwicky 193O something holds back distant fast-moving galaxies. Detailed studies gives the same problems for stars inside galaxies. Nonluminous matter 25% is required. Candidates: netrino less than 1%, axions? WIMPs Weakly Interacting Massive Particles from big bang SUSY: photino,zino,higgsino...etc.

51 Dark energy Accelrating expansion of the universe Type Ia supernova distance – recessional speed light yield – doppler effect The observed size of acceleration requires 7O % plus energy by cosmological constant. New survey satelite SNAP SuperNova/Acceleration Probe This amount is the same what is reiquired for flat universe!! COBE, WMAP confirm flatness
