Observation of a new boson with mass near 125 GeV in pp collisions at √=7 and 8 TeV
(Springer, 2013)A detailed description is reported of the analysis used by the CMS Collaboration in the search for the standard model Higgs boson in pp collisions at the LHC, which led to the observation of a new boson. The data sample ... 
Observation of chargedependent azimuthal correlations in pPb collisions and its implication for the search for the chiral magnetic effect
(American Physical Society, 201703)Chargedependent azimuthal particle correlations with respect to the secondorder event plane in pPb and PbPb collisions at a nucleonnucleon centerofmass energy of 5.02 TeV have been studied with the CMS experiment at ... 
Observation of sequential Υ suppression in PbPb collisions
(American Physical Society, 201211)The suppression of the individual Υ(nS) states in PbPb collisions with respect to their yields in pp data has been measured. The PbPb and pp data sets used in the analysis correspond to integrated luminosities of 150μb 1 ... 
Observation of the rare B0s→μ+μ decay from the combined analysis of CMS and LHCb data
(Nature Publishing Group, 201506)The standard model of particle physics describes the fundamental particles and their interactions via the strong, electromagnetic and weak forces. It provides precise predictions for measurable quantities that can be tested ... 
Observation of top quark pairs produced in association with a vector boson in pp collisions at √s = 8 TeV
(Springer, 2016)Measurements of the cross sections for top quark pairs produced in association with a W or Z boson are presented, using 8 TeV pp collision data corresponding to an integrated luminosity of 19.5 fb1, collected by the CMS ... 
Observation of Y(1S) pair production in protonproton collisions at √s=8 TeV
(Springer, 201705)Pair production of Y(1S) mesons is observed at the LHC in protonproton collisions at s=8 TeV by the CMS experiment in a data sample corresponding to an integrated luminosity of 20.7 fb−1. Both Y(1S) candidates are fully ... 
Observation of Z decays to four leptons with the CMS detector at the LHC
(Springer, 2012)The first observation of the Z boson decaying to four leptons in protonproton collisions is presented. The analyzed data set corresponds to an integrated luminosity of 5.02 fb1 at s=7 TeV collected by the CMS detector ... 
Obtaining a secure and efficient key agreement protocol from (H)MQV and NAXOS
(Springer, 200803)LaMacchia, Lauter and Mityagin recently presented a strong security definition for authenticated key agreement strengthening the wellknown CanettiKrawczyk definition. They also described a protocol, called NAXOS, that ... 
Obtaining a secure and efficient key agreement protocol from (H)MQV and NAXOS (extended version)
(International Association for Cryptologic Research, 2009)LaMacchia, Lauter and Mityagin recently presented a strong security definition for authenticated key agreement strengthening the wellknown CanettiKrawczyk definition. They also described a protocol, called NAXOS, that ... 
On a 2+1dimensional WhithamBroerKaup system: A resonant NLS connection
(WileyBlackwell, 201108)It is established that the WhithamBroerKaup shallow water system and the "resonant" nonlinear Schrödinger equation are equivalent. A symmetric integrable 2+1dimensional version of the WhithamBroerKaup system is ... 
On a recent generalization of semiperfect rings
(Cambridge University Press, 200810)In a recent paper by Wang and Ding, it was stated that any ring which is generalized supplemented as a left module over itself is semiperfect. The purpose of this note is to show that Wang and Ding's claim is not true and ... 
On classical and quantum qoscillators in the relativistic theory
(Springer, 200411)The factorization method, applied to the finitedifference Schrödinger equation in the relativistic configurational space, allows to consider the qdeformations as a relativistic effect. In particular, different factorizations ... 
On density theorems for rings of Krull type with zero divisors
(TÜBİTAK, 201405)Let R be a commutative ring and I(R) denote the multiplicative group of all invertible fractional ideals of R, ordered by A ≥ B if and only if B ⊆ A. If R is a Marot ring of Krull type, then R(Pi), where {Pi}i∈I are a ... 
On the application of the Expfunction method to nonlinear differentialdifference equations
(Elsevier, 201206)When applying the Expfunction method to nonlineardifferential difference equations, Bekir (2010) [1] reported incorrect results. © 2012 Elsevier Inc. All rights reserved. 
On the application of the Expfunction method to the KP equation for Nsoliton solutions
(Elsevier, 201211)We observe that the form of the KadomstevPetviashvili equation studied by Yu (2011) [S. Yu, Nsoliton solutions of the KP equation by Expfunction method, Appl. Math. Comput. (2011) doi:10.1016/j.amc.2010.12.095] is ... 
On the choice of stabilizing subgrid for convectiondiffusion problem on rectangular grids
(Elsevier, 201006)A stabilizing subgrid which consists of a single additional node in each rectangular element is analyzed for solving the convectiondiffusion problem, especially in the case of small diffusion. We provide a simple recipe ... 
On the importance of publickey validation in the MQV and HMQV key agreement protocols
(Springer, 2006)HMQV is a hashed variant of the MQV key agreement protocol proposed by Krawczyk at CRYPTO 2005. In this paper, we present some attacks on HMQV and MQV that are successful if public keys are not properly validated. In ...
