“…Supersymmetry [14][15][16][17][18][19][20][21][22] postulates the existence of a new supersymmetric partner for each SM particle, differing by half a unit of spin from, but with gauge coupling identical to those of their SM counterparts. Collisions of protons could result in pair production of squarks,q, which could decay to a SM quark and a neutralinoχ 0 1 ; the neutralino is assumed to be stable in R-parity-conserving models [23].…”

Results of a search for new phenomena in events with an energetic photon and large missing transverse momentum with the ATLAS experiment at the LHC are reported. Data were collected in proton-proton collisions at a center-of-mass energy of 8 TeV and correspond to an integrated luminosity of 20.3 fb −1 . The observed data are well described by the expected Standard Model backgrounds. The expected (observed) upper limit on the fiducial cross section for the production of events with a photon and large missing transverse momentum is 6.1 (5.3) fb at 95% confidence level. Exclusion limits are presented on models of new phenomena with large extra spatial dimensions, supersymmetric quarks, and direct pair production of dark-matter candidates.

“…Supersymmetry (SUSY) [1][2][3][4][5][6][7][8][9] is a space-time symmetry that postulates the existence of new SUSY particles, or sparticles, with spin (S) differing by one half-unit with respect to their standard model (SM) partners. In supersymmetric extensions of the SM, each SM fermion (boson) is associated with a SUSY boson (fermion), having the same quantum numbers as its partner except for S. The scalar superpartners of the SM fermions are called sfermions (comprising the sleptons,l, the sneutrinos,ν, and the squarks,q), while the gluons have fermionic superpartners called gluinos (g).…”

Search for supersymmetry in events with four or more leptons ins=8 TeVppcollisions with the ATLAS detector

Results from a search for supersymmetry in events with four or more leptons including electrons, muons and taus are presented. The analysis uses a data sample corresponding to 20.3 fb −1 of proton-proton collisions delivered by the Large Hadron Collider at ffiffi ffi s p ¼ 8 TeV and recorded by the ATLAS detector.Signal regions are designed to target supersymmetric scenarios that can be either enriched in or depleted of events involving the production of a Z boson. No significant deviations are observed in data from standard model predictions and results are used to set upper limits on the event yields from processes beyond the standard model. Exclusion limits at the 95% confidence level on the masses of relevant supersymmetric particles are obtained. In R-parity-violating simplified models with decays of the lightest supersymmetric particle to electrons and muons, limits of 1350 and 750 GeV are placed on gluino and chargino masses, respectively. In R-parity-conserving simplified models with heavy neutralinos decaying to a massless lightest supersymmetric particle, heavy neutralino masses up to 620 GeV are excluded. Limits are also placed on other supersymmetric scenarios.

“…This can be solved by the presence of new physics at a scale NP M Pl since this new physics would introduce additional quantum corrections to the Higgs mass, and thus potentially cancel the top loop. This occurs for instance in models of Supersymmetry [7][8][9][10][11][12][13][14][15] (SUSY) where the spin-0 partner of the top quark, the stop, cancels the large top quark loop [16][17][18][19][20][21]. However, for this cancellation to work the masses of the relevant SUSY partners must be near the weak scale [22,23].…”

LHC – perspectives at the energy frontier

After a design and construction phase that lasted more than two decades, the Large Hadron Collider (LHC) started its first run in 2010 and after just over two years, the discovery of the Higgs boson at the LHC was announced. In the future the LHC collision energy will be increased by nearly a factor of two, and the dataset will be increased by more than a factor of 100. These improvements dramatically increase the potential for finding new physics at the weak scale via either precision measurements or direct searches or both. The LHC is in a unique position to directly explore the weak energy scale and shed light on some of the biggest puzzles in nature, e.g. the origin of Dark Matter or the hierarchy problem.
