, 1996 In the first half of the paper we study spurious regressions in panel data when the cross-section and time-series dimensions are comparable. Asymptotic properties of the least-squares dummy variable (LSDV) estimator and other conventional statistics are ...

Top++: A program for the calculation of the top-pair cross-section at hadron colliders [PDF]
Computer Physics Communications, 2011 We present the program Top++ for the numerical evaluation of the total inclusive cross-section for producing top quark pairs at hadron colliders. The program calculates the cross-section in (a) fixed order approach with exact next-to-next-to leading ...

Entanglement Wedge Cross Section from the Dual Density Matrix. [PDF]
Physical Review Letters, 2018 We define a new information theoretic quantity called odd entanglement entropy (OEE) which enables us to compute the entanglement wedge cross section in holographic conformal field theories (CFTs). The entanglement wedge cross section has been introduced

First measurement of elastic, inelastic and total cross-section at $$\sqrt{s}=13$$s=13 TeV by TOTEM and overview of cross-section data at LHC energies [PDF]
The European Physical Journal C, 2017 The TOTEM collaboration has measured the proton–proton total cross section at $$\sqrt{s}=13~\hbox {TeV}$$s=13TeV with a luminosity-independent method. Using dedicated $$\beta ^{*}=90~\hbox {m}$$β∗=90m beam optics, the Roman Pots were inserted very close ...

EPJ Web of Conferences, 2017 To estimate the lifetime and the radiation dose of the proton beam window used in the spallation neutron source at J-PARC, it is necessary to understand the accuracy of the production cross section of 3-GeV protons.

Cross section of the 197Au(n,2n)196Au reaction
EPJ Web of Conferences, 2017 The 197Au(n,2n)196Au reaction cross section has been measured at two energies, namely at 17.1 MeV and 20.9 MeV, by means of the activation technique, relative to the 27Al(n,α)24Na reference reaction cross section.

Comparing Cross-Section and Time-Series Factor Models
The Review of financial studies, 2019 We use the cross-section regression approach of Fama and MacBeth (1973) to construct cross-section factors corresponding to the time-series factors of Fama and French (2015).

Physics Letters BThe Giant Dipole Resonance (GDR) in 51V has been a long-term conflicting interpretation, with existing photoneutron cross section data suggesting either a single peak or a pronounced splitting, leading to opposite conclusions on nuclear deformation.
