gm2calc - GM2Calc 2.0.0

New features

  • Calculation of the anomalous magnetic moment of the muon in the Two-Higgs-Doublet Model (2HDM) at the 1- and leading 2-loop level. The implemented expressions are taken from [JHEP 01 (2017) 007]. See the README file and examples/example-thdm.{c,cpp,m} for examples.

Fixed bugs

  • Bugfix (commit 205f5cf): Ensure that MSSM Goldstone bosons are always at the first position in the Higgs multiplets. This change has no effect on the value of a_mu in the MSSM.

  • Bugfix (commit b72cc64): Avoid a NaN in the 2-loop sfermionic MSSM contributions when the f_sferm function is called with z = 0 as argument. This case appears when a stop, sbottom or stau is massless.

  • Bugfix (commit 906bbca): Avoid a NaN in the 2-loop sfermionic MSSM contributions when the f_S function is called with z = 0 as argument. This case appears when a chargino is massless.

  • Bugfix (commit 5bee954): Avoid a NaN in the 2-loop sfermionic MSSM contributions when the f_PS function is called with z = 0 as argument. This case appears when a chargino is massless.

- C++
Published by Expander almost 6 years ago

gm2calc - GM2Calc 1.6.0

New features

  • Feature: New cmake/FindGM2Calc.cmake file.

Fixed bugs

  • Bugfix (commit c06f713): The function find_right_like_smuon() has been corrected, which finds the most right-like smuon. This bugfix affects only the SLHA input (the GM2Calc-specific input is not affected). On tested parameter points that are affected, the value of amu changes by around 0.01%.

  • Bugfix (commit 5e020ee): In case of SLHA input, the neutralino mixing matrix is now read from the NMIX block and used to determine the bino-like neutralino. This change fixes convergence problems when converting the DR-bar input parameters to the on-shell scheme.

Changes

  • Change: Separate public from private headers. The public headers are located in include/gm2calc/, while the private headers are located nearby the respective source files. The public headers must be included as

    #include "gm2calc/gm2_version.h"

  • Change: Private header and source files renamed:

    • Model-specific source files are named as MSSMNoFV_onshell*.{h,hpp,cpp}.
    • Files specific to the calculation of (g-2) are named as gm2_*.{h,hpp,cpp}.

  • Change (commit f276703): In case the SLHA input contains multiple HMIX blocks, use the last one to define the renormalization scale. Input parameters are then searched for in blocks with that renormalization scale.

  • Change (commit 9907e86): The Mathematica interface now returns Indeterminate for amu in case there is a problem with the calculation.

  • Change (commit aad392c): Update FindMathematica to version 3.2.7

  • Change (commit 059744f): Performance improvement by avoiding frequent re-calculation of mb(MZ,DR-bar).

  • Change (commit b38eab7): Update of default fine-structure constant from PDG (2019) and [arXiv:1802.02995].

  • Change (commit 67b39a5): New error message when tan(beta) is too large, resulting in floating point overflows.

  • Change (commit 9fdc594, e73c63a): Performance improvement of reading SLHA input.

  • Change (commits 4ad9d95, 445ea1c, c7a5e9d): More stingent test of GM2Calc configuration options. Bail out if invalid options are given.

  • Change (commits ea03df9, 32df289, 6325c07, 438b421): Performance improvement of conversion of SLHA input to GM2Calc-specific on-shell scheme.

  • Change (commits d54714f, cf8e702, ec60044, da8d948): Make GM2Calc compatible to be used as CMake sub-project.

  • Change (commit 77615d7): Verbose, error and warning messages are now written to cerr. This allows to separate the physics output from the informational messages.

  • Change (commits ee1eab3, 0635231, 576afcb): Avoid redundant error messages to stdout/stderr. This significantly improves the performance of parameter scans using the Mathematica interface, where frequent flushing of the stdout/stderr buffers is expensive.

  • Change: Many stylistic internal improvements; fixes of clang-tidy warnings.

gm2calc - GM2Calc 1.5.0

New features

  • Feature: New make install target, so GM2Calc can be installed. The installation includes the executable gm2calc.x, the GM2Calc library, the public headers and a corresponding gm2calc.pc file for pkg-config.

Example:

   cmake -DCMAKE_INSTALL_PREFIX=${HOME}/.local/ ..
   make
   make install

  • Feature: The required Boost and Eigen libraries can now be installed with Conan:

    mkdir -p build cd build

    # install dependencies conan install ..

    # invoke cmake as usual cmake ..

Changes

  • Change (commit 577815e): gm2calc::Error now inherits from std::runtime_error.

  • Change (commit 674cc13): If there is more than one entry with the same key in an SLHA block, use the last one.
