    Differential cross sections as a function of transverse momentum pT are presented for the production of ϒ(nS) (n = 1, 2, 3) states decaying into a pair of muons. Data corresponding to an integrated luminosity of 4.9fb−1 in pp collisions at s=7TeV were collected with the CMS detector at the LHC. The analysis selects events with dimuon rapidity |y| <1.2 and dimuon transverse momentum in the range 10

    A search is presented for long-lived charged particles that decay within the CMS detector and produce the signature of a disappearing track. Disappearing tracks are identified as those with little or no associated calorimeter energy deposits and with missing hits in the outer layers of the tracker. The search uses proton-proton collision data recorded at TeV that corresponds to an integrated luminosity of 19.5 fb−1. The results of the search are interpreted in the context of the anomaly-mediated supersymmetry breaking (AMSB) model. The number of observed events is in agreement with the background expectation, and limits are set on the cross section of direct electroweak chargino production in terms of the chargino mass and mean proper lifetime. At 95% confidence level, AMSB models with a chargino mass less than 260 GeV, corresponding to a mean proper lifetime of 0.2 ns, are excluded.

    Search for physics beyond the standard model in events with two leptons, jets, and missing transverse momentum in pp collisions at √S= 8 TeV
    Khachatryan, V.; Sirunyan, A. M.; Tumasyan, A.; J. Karancsi; A. Makovec, P. Raics, Z.L. Trocsanyi, B. Ujvari; Karancsi János (1987-) (fizikus); Makovec Alajos (1987-) (fizikus); Raics Péter (1944-) (fizikus); Trócsányi Zoltán (1961-) (fizikus); Ujvári Balázs (1977-) (Fizikus / PhD); Debreceni Egyetem
    A search is presented for physics beyond the standard model in final states with two opposite-sign same-flavor leptons, jets, and missing transverse momentum. The data sample corresponds to an integrated luminosity of 19.4 fb−1 of proton-proton collisions at √S= 8 TeV collected with the CMS detector at the CERN LHC in 2012. The analysis focuses on searches for a kinematic edge in the invariant mass distribution of the oppositesign same-flavor lepton pair and for final states with an on-shell Z boson. The observations are consistent with expectations from standard model processes and are interpreted in terms of upper limits on the production of supersymmetric particles.

    Searches for a heavy scalar boson H decaying to a pair of 125 GeV Higgs bosons hh or for a heavy pseudoscalar boson A decaying to Zh, in the final states with h → ττ

Ujvari; Karancsi János (1987-) (fizikus); Bartók Márton (2024-) (xxx); Makovec Alajos (1987-) (fizikus); Raics Péter (1944-) (fizikus); Trócsányi Zoltán (1961-) (fizikus); Ujvári Balázs (1977-) (Fizikus / PhD); Fizikai Intézet -- 749; TTK; Debreceni Egyetem
    A search for a heavy scalar boson H decaying into a pair of lighter standard-model-like 125 GeV Higgs bosons hh and a search for a heavy pseudoscalar boson A decaying into a Z and an h boson are presented. The searches are performed on a data set corresponding to an integrated luminosity of 19.7 fb−1 of pp collision data at a centre-of-mass energy of 8 TeV, collected by CMS in 2012. A final state consisting of two τ leptons and two b jets is used to search for the H→hh decay. A final state consisting of two τ leptons from the h boson decay, and two additional leptons from the Z boson decay, is used to search for the decay A→Zh. The results are interpreted in the context of two-Higgs-doublet models. No excess is found above the standard model expectation and upper limits are set on the heavy boson production cross sections in the mass ranges 260
