"A Supersymmetry Primer" is
my introduction to supersymmetry.
Some pedagogical summer school lectures I've given: slides for the PreSUSY International School 2021 and notes for my TASI 2011 lectures on twocomponent fermions and supersymmetry. TSIL (Twoloop Selfenergy Integral Library) and 3VIL (3loop Vacuum Integral Library) are computer program libraries that Dave Robertson and I wrote and maintain. They perform the numerical computation of Feynman integrals for, respectively, 2loop selfenergy and 3loop vacuum diagrams, with arbitrary masses. TSIL is based on the papers hepph/0307101 and hepph/0501132, while 3VIL is based on hepph/1610.07720. SMDR (Standard Model in Dimensional Regularization) is a computer program library for calculations in the tadpolefree pure MSbar scheme in the Standard Model of particle physics. This mean that it treats the MSbar Lagrangian parameters as the fundamental inputs, and the Higgs vacuum expectation value (VEV) is defined as the minimum of the Landau gauge effective potential, so that tadpole diagrams vanish. SMDR computes the stateoftheart multiloop relations between the MSbar inputs and the onshell observables to which they most closely correspond. It also includes all known contributions to renormalization group equations and threshold matching relations for the gauge couplings, fermion masses and Yukawa couplings. SMDR was also written with Dave Robertson, and is an application of TSIL and 3VIL. The paper announcing SMDR is available from the arXiv.org preprint archive as 1907.02500. Another application of TSIL is the 2loop SUSYQCD contributions to the gluino and squark pole masses, recently implemented in SOFTSUSY 3.7.0 by Ben Allanach, Dave Robertson, Roberto Ruiz de Austri, and me. For a description of this, see the manual: 1601.06657. Here is the web page (including errata, and a version with the +++ metric) for the review paper 0812.1594, "Twocomponent spinor techniques and Feynman rules for quantum field theory and supersymmetry", by Herbi K. Dreiner, Howard E. Haber, and me. The current v5 is very close to the one published in Physics Reports.
