Detailed Report on the Measurement of the Positive Muon Anomalous Magnetic Moment to 0.20 ppm / Muon g-2 Collaboration
We present details on a new measurement of the muon magnetic anomaly, $a_\mu = (g_\mu -2)/2$. [...]

First Result from the Alpha Magnetic Spectrometer on the International Space Station: Precision Measurement of the Positron Fraction in Primary Cosmic Rays of 0.5–350 GeV / AMS Collaboration
A precision measurement by the Alpha Magnetic Spectrometer on the International Space Station of the positron fraction in primary cosmic rays in the energy range from 0.5 to 350 GeV based on 6.8×106 positron and electron events is presented. The very accurate data show that the positron fraction is steadily increasing from 10 to ∼250  GeV, but, from 20 to 250 GeV, the slope decreases by an order of magnitude. [...]

Modular Exercises for Four-Point Blocks -- I / Cheng, Miranda C.N. (Amsterdam U., Inst. Math. ; Amsterdam U.) ; Gannon, Terry (U. Alberta (main)) ; Lockhart, Guglielmo (Amsterdam U. ; CERN)
The well-known modular property of the torus characters and torus partition functions of (rational) vertex operator algebras (VOAs) and 2d conformal field theories (CFTs) has been an invaluable tool for studying this class of theories. [...]

Precision Measurement of the Proton Flux in Primary Cosmic Rays from Rigidity 1 GV to 1.8 TV with the Alpha Magnetic Spectrometer on the International Space Station / Aguilar, M (Madrid, CIEMAT) ; Aisa, D (INFN, Perugia ; Perugia U.) ; Alpat, B (INFN, Perugia) ; Alvino, A (INFN, Perugia) ; Ambrosi, G (INFN, Perugia) ; Andeen, K (KIT, Karlsruhe, IKP) ; Arruda, L (LIP, Lisbon) ; Attig, N (IAS, Julich ; JARA, Aachen) ; Azzarello, P (INFN, Perugia ; Geneva U.) ; Bachlechner, A (RWTH Aachen U. ; JARA, Aachen) et al. /AMS
A precise measurement of the proton flux in primary cosmic rays with rigidity (momentum/charge) from 1 GV to 1.8 TV is presented based on 300 million events. Knowledge of the rigidity dependence of the proton flux is important in understanding the origin, acceleration, and propagation of cosmic rays. [...]

Precision Measurement of the ($e^+ + e^−$) Flux in Primary Cosmic Rays from 0.5 GeV to 1 TeV with the Alpha Magnetic Spectrometer on the International Space Station / AMS Collaboration
We present a measurement of the cosmic ray ($e^+ + e^−$) flux in the range 0.5 GeV to 1 TeV based on the analysis of 10.6 million ($e^+ + e^−$) events collected by AMS. The statistics and the resolution of AMS provide a precision measurement of the flux. [...]

Electron and Positron Fluxes in Primary Cosmic Rays Measured with the Alpha Magnetic Spectrometer on the International Space Station / AMS Collaboration
Precision measurements by the Alpha Magnetic Spectrometer on the International Space Station of the primary cosmic-ray electron flux in the range 0.5 to 700 GeV and the positron flux in the range 0.5 to 500 GeV are presented. The electron flux and the positron flux each require a description beyond a single power-law spectrum. [...]

High Statistics Measurement of the Positron Fraction in Primary Cosmic Rays of 0.5–500 GeV with the Alpha Magnetic Spectrometer on the International Space Station / AMS Collaboration
A precision measurement by AMS of the positron fraction in primary cosmic rays in the energy range from 0.5 to 500 GeV based on 10.9 million positron and electron events is presented. This measurement extends the energy range of our previous observation and increases its precision. [...]
