Observation of χcJ4KS0 / Ablikim, M. ; Achasov, M. N. ; Ahmed, S. ; Albrecht, M. ; et al
By analyzing (448.1±2.9)×106 ψ(3686) events collected with the BESIII detector operating at the BEPCII collider, the decays of χcJ4KS0 (J=0, 1, 2) are observed for the first time with statistical significances of 26.5σ, 5.9σ and 11.4σ, respectively. [...]

Measurement of the mass and production rate of Ξb baryons / Aaij, R. ; Abellán Beteta, C. ; Adeva, B. ; Adinolfi, M. ; et al
The first measurement of the production rate of Ξb baryons in pp collisions relative to that of Λb0 baryons is reported, using data samples collected by the LHCb experiment, and corresponding to integrated luminosities of 1, 2 and 1.6 fb1 at s=7, 8 and 13 TeV, respectively. [...]

Response to an external magnetic field of the decay rate of a neutral scalar field into a charged fermion pair / Jaber-Urquiza, Jorge ; Piccinelli, Gabriella ; Sánchez, Angel
In this work, we explore the effects of a weak magnetic field on the decay process of a neutral scalar boson into a pair of charged fermions in vacuum. [...]

Sterile neutrino origin for the upward directed cosmic ray showers detected by ANITA / Cherry, John F. ; Shoemaker, Ian M.
The ANITA balloon experiment has recently observed several EeV cascade events at an angle below the horizon that renders any Standard Model (SM) interpretation unlikely as the Earth is significantly opaque to all SM particles at such energies. [...]

Multiparticle potentials from lightlike Wilson lines in quark-gluon plasmas: A generalized relation of in-medium splitting rates to jet-quenching parameters q^ / Arnold, Peter
A powerful historical insight about the theory of in-medium showering in QCD backgrounds was that splitting rates can be related to a parameter q^ that characterizes the rate of transverse-momentum kicks to a high-energy particle from the medium. [...]

Energy evolution and the Bose-Einstein enhancement for double parton densities / Gotsman, E. ; Levin, E.
In this paper we show that Bose-Einstein enhancement generates strong correlations which, in the Balitsky-Fadin-Kuraev-Lipatov (BFKL) evolution, increase with energy. [...]

Flavor of cosmic neutrinos preserved by ultralight dark matter / Farzan, Yasaman ; Palomares-Ruiz, Sergio
Within the standard propagation scenario, the flavor ratios of high-energy cosmic neutrinos at neutrino telescopes are expected to be around the democratic benchmark resulting from hadronic sources, (1/3:1/3:1/3). [...]

Evidence for charm-bottom tetraquarks and the mass dependence of heavy-light tetraquark states from lattice QCD / Francis, Anthony ; Hudspith, Renwick J. ; Lewis, Randy ; Maltman, Kim
We continue our study of heavy-light four-quark states and find evidence from lattice QCD for the existence of a strong-interaction-stable I(JP)=0(1+) udc¯b¯ tetraquark with mass in the range of 15 to 61 MeV below D¯B* threshold. [...]
