Testing the doubly charged charm–strange tetraquarks / Agaev, S. S. ; Azizi, K. ; Sundu, H.
The spectroscopic parameters and decay channels of the doubly charged scalar, pseudoscalar and axial-vector charm–strange tetraquarks Zc¯s=[sd][u¯c¯] are explored within framework of the QCD sum rule method. [...]

Search for standard model production of four top quarks with same-sign and multilepton final states in proton–proton collisions at s=13TeV / Sirunyan, A. M. ; Tumasyan, A. ; Adam, W. ; Ambrogi, F ; et al
A search for standard model production of four top quarks ( tt¯tt¯ ) is reported using events containing at least three leptons ( e,μ ) or a same-sign lepton pair. [...]

Stability under scalar perturbations and quasinormal modes of 4D Einstein–Born–Infeld dilaton spacetime: exact spectrum / Destounis, Kyriakos ; Panotopoulos, Grigoris ; Rincón, Ángel
We study the stability under scalar perturbations, and we compute the quasinormal modes of the Einstein–Born–Infeld dilaton spacetime in 1+3 dimensions. [...]

Measurement of longitudinal flow decorrelations in Pb+Pb collisions at sNN=2.76 and 5.02 TeV with the ATLAS detector / Aaboud, M. ; Aad, G. ; Abbott, B. ; Abdinov, O. ; et al
Measurements of longitudinal flow correlations are presented for charged particles in the pseudorapidity range |η|<2.4 using 7 and 470 μb-1 of Pb+Pb collisions at sNN=2.76 and 5.02 TeV, respectively, recorded by the ATLAS detector at the LHC. [...]

Baryon number fluctuations and the phase structure in the PNJL model / Shao, Guo-yun ; Tang, Zhan-duo ; Gao, Xue-yan ; He, Wei-bo
We investigate the kurtosis and skewness of net-baryon number fluctuations in the Polyakov loop extended Nambu–Jona-Lasinio (PNJL) model, and discuss the relations between fluctuation distributions and the phase structure of quark-gluon matter. [...]

Interference effect as resonance killer of newly observed charmoniumlike states Y (4320) and Y (4390) / Chen, Dian-Yong ; Liu, Xiang ; Matsuki, Takayuki
In this letter, we decode the newly observed charmoniumlike states, Y (4320) and Y (4390), by introducing interference effect between ψ(4160) and ψ(4415) , which plays a role of resonance killer for Y (4320) and Y (4390). [...]

Conserved charges of minimal massive gravity coupled to scalar field / Setare, M. R. ; Adami, H.
Recently, the theory of topologically massive gravity non-minimally coupled to a scalar field has been proposed, which comes from the Lorentz–Chern–Simons theory (JHEP 06, 113, 2015 ), a torsion-free theory. [...]

Scalar radiation from a radially infalling source into a Schwarzschild black hole in the framework of quantum field theory / Oliveira, Leandro A. ; Crispino, Luís C. B. ; Higuchi, Atsushi
We investigate the radiation to infinity of a massless scalar field from a source falling radially towards a Schwarzschild black hole using the framework of the quantum field theory at tree level. [...]
