Combination of measurements of the top quark mass from data collected by the ATLAS and CMS experiments at $\sqrt{s}=7$ and 8 TeV / ATLAS Collaboration
A combination of fifteen top quark mass measurements performed by the ATLAS and CMS experiments at the LHC is presented. The data sets used correspond to an integrated luminosity of up to 5 and 20$^{-1}$ of proton-proton collisions at center-of-mass energies of 7 and 8 TeV, respectively. [...]

Measurements of the suppression and correlations of dijets in Xe+Xe collisions at $\sqrt{s_{NN}}$ = 5.44 TeV / ATLAS Collaboration
Measurements of the suppression and correlations of dijets is performed using 3 $\mu$b$^{-1}$ of Xe+Xe data at $\sqrt{s_{\mathrm{NN}}} = 5.44$ TeV collected with the ATLAS detector at the LHC. Dijets with jets reconstructed using the $R=0.4$ anti-$k_t$ algorithm are measured differentially in jet $p_{\text{T}}$ over the range of 32 GeV to 398 GeV and the centrality of the collisions. [...]

Evidence for the charge asymmetry in $pp \rightarrow t\bar{t}$ production at $\sqrt{s}= 13$ TeV with the ATLAS detector / ATLAS Collaboration
Inclusive and differential measurements of the top-antitop ($t\bar{t}$) charge asymmetry $A_\text{C}^{t\bar{t}}$ and the leptonic asymmetry $A_\text{C}^{\ell\bar{\ell}}$ are presented in proton-proton collisions at $\sqrt{s} = 13$ TeV recorded by the ATLAS experiment at the CERN Large Hadron Collider. The measurement uses the complete Run 2 dataset, corresponding to an integrated luminosity of 139 fb$^{-1}$, combines data in the single-lepton and dilepton channels, and employs reconstruction techniques adapted to both the resolved and boosted topologies.

Combination of inclusive top-quark pair production cross-section measurements using ATLAS and CMS data at $\sqrt{s}= 7$ and 8 TeV / ATLAS Collaboration
A combination of measurements of the inclusive top-quark pair production cross-section performed by ATLAS and CMS in proton-proton collisions at centre-of-mass energies of 7 and 8 TeV at the LHC is presented. The cross-sections are obtained using top-quark pair decays with an opposite-charge electron-muon pair in the final state and with data corresponding to an integrated luminosity of about 5 fb$^{-1}$ at $\sqrt{s}=7$ TeV and about 20 fb$^{-1}$ at $\sqrt{s}=8$ TeV for each experiment.

Observation of $WWW$ production in $pp$ collisions at $\sqrt{s} = 13$ TeV with the ATLAS detector / ATLAS Collaboration
This Letter reports the observation of $WWW$ production and a measurement of its cross section using 139 $\text{fb}^{-1}$ of proton-proton collision data recorded at a center-of-mass energy of 13 TeV by the ATLAS detector at the Large Hadron Collider. Events with two same-sign leptons (electrons or muons) and at least two jets, as well as events with three leptons, are selected. [...]

Constraints on the Intrinsic Charm Content of the Proton from Recent ATLAS Data / Lykasov, Gennady (Dubna, JINR) ; Brodsky, Stanley J (SLAC) ; Bednyakov, V A (Dubna, JINR) ; Lipatov, A V (SINP, Moscow) ; Smiesko, J (Comenius U.) ; Tokar, S (Comenius U.) /ATLAS Collaboration
We investigate the possibility to constrain the intrinsic charm probability in proton $w_c$ using first ATLAS data on the associated production of prompt photons and charm-quark jets in $pp$ collisions at $\sqrt{s}$ = 8 TeV. The upper limit on the intrinsic charm probability in proton $w_{ul}$ < 1.93% is obtained at the 68% confidence level. [...]

JINR Participation in the Physics Program of the ATLAS Experiment in 2015–2019 Period / Bednyakov, V A (Dubna, JINR) ; Khramov, E V (Dubna, JINR)
The main purpose of the international ATLAS experiment—is the study of the proton-proton interactions at unprecedented energies of the LHC collider (from 7 to 14 TeV in center-of-mass system of colliding protons). In particular, the detailed probationof the Standard Model, its application limits, search for solutions of the key problems of the current stage of physics and astrophysics , such as origin of the elementary particles masses, nature of dark matter in the Universe, existence of extra dimensions and others are carried out with the ATLAS.

High-precision limits on $W–W'$ and $Z–Z'$ mixing from diboson production using the full LHC Run 2 ATLAS data set / Pankov, A.A. (Gomel State Tech. U., ICTP ; Minsk, Inst. Nucl. Problems ; Dubna, JINR) ; Osland, P. (Bergen U.) ; Serenkova, I.A. (Gomel State Tech. U., ICTP) ; Bednyakov, V.A. (Dubna, JINR)
The full ATLAS Run 2 data set with time-integrated luminosity of 139 fb$^{-1}$ in the diboson channels in hadronic final states is used to probe a simple model with an extended gauge sector (EGM), proposed by Altarelli et al., and often taken as a convenient benchmark by experimentalists. This model accommodates new charged $W'$ and neutral $Z'$ vector bosons with modified trilinear Standard Model gauge couplings, decaying into electroweak gauge boson pairs $WZ$ or $WW$, where $W$/$Z$ decay hadronically.

Results of searches for Dubna resonance Z* in dimuon channel in ATLAS data / Yeletskikh, I V (Dubna, JINR) ; Bednyakov, V A (Dubna, JINR)
Results of searches for a new heavy boson Z* performed by the ATLAS Dubna team are presented. They are based upon an analysis of events with two oppositely charged muons in the final state collected by the ATLAS detector in 2012 in proton-proton collisions at the Large Hadron Collider with a center-of-mass energy of 8 TeV and integral luminosity of 20 fb$^{−1}$.

Forward heavy flavour production in p-p collisions at LHC and intrinsic quark components in proton / Lykasov, G.I. (Dubna, JINR) ; Bednyakov, V.A. (Dubna, JINR) ; Pikelner, A.F. (Dubna, JINR) ; Zimine, N.I. (Dubna, JINR ; CERN)
The LHC data on the forward heavy flavour hadron production can be a new unique source for estimation of intrinsic charm and bottom contributions to the proton. For example, we analyze the forward heavy baryon production, namely $\Lambda_b$-baryon, within the soft QCD quark gluon string model and present the predictions for observables which could be measured at the LHC.
