[Flexiblesusy-announce] FlexibleSUSY version 1.2.3

[Alexander Voigt]

Dear all,

I'd like to announce FlexibleSUSY version 1.2.3, which has been
released today, 18 October 2015.  It can be downloaded from

   https://flexiblesusy.hepforge.org/


What's new
==========

  * New model SplitMSSM, which implements low-energy EFT of the MSSM
    where the sfermions and one Higgs doublet have been integrated out.
    The model implements the 1- and 2-loop matching conditions from
    arxiv:1407.4081.  The Higgs pole mass is calculated at complete
    1-loop order plus 2-loop contributions O(alpha_t^2) and O(alpha_t
    alpha_s) from arxiv:1205.6497 plus 3-loop leading-log contribution
    from the gluino O(alpha_t alpha_s^2) (arxiv:1312.5220).

  * New model HSSUSY, which implements a high-scale SUSY scenario,
    where the sfermions, the gauginos, the Higgsinos and one Higgs
    doublet have been integrated out, leaving the Standard Model as
    low-energy EFT.  The model uses the 3-loop Standard Model RGEs
    (arxiv:1303.4364, arXiv:1307.3536) and implements the 1- and 2-loop
    matching conditions to lambda(MSUSY) from arxiv:1407.4081.
    Furthermore, the 1-loop matching conditions O(alpha_b) and
    O(alpha_tau) as well as the 2-loop matching condition O(alpha_t^2)
    from SUSYHD (arxiv:1504.05200) are implemented.  The Higgs pole
    mass is calculated at complete 1-loop order plus 2-loop
    contributions O(alpha_t^2) and O(alpha_t alpha_s) from
    arxiv:1205.6497.  The calculation of the Higgs pole mass in the
    HSSUSY model coincides with the one obtained with SUSYHD 1.0.2 with
    a relative deviation of < 0.15%.

  * Feature: Allow adding 3-loop gluino contribution to Higgs
    self-energy in split-SUSY models with a physical singlet Higgs.
    The 3-loop gluino contribution is enabled by default in the
    SplitMSSM.  To enable the 3-loop gluino contribution set
    UseHiggs3LoopSplit = True in the model file.

  * Adding support for If[] and Which[] statements at the r.h.s. of
    contraints.  In addition, the IsClose[a,b,eps] and
    IsCloseRel[a,b,eps] functions have been added to allow for a
    comparison of parameters.


Changes
=======

  * The FlexibleSUSY test suite is no longer shipped with the release
    tarball.  It can be obtained from the official git repository at
    https://github.com/FlexibleSUSY/FlexibleSUSY .

  * The `test' and `examples' modules are no longer loaded into the
    makefile by default.  To load them, run ./configure
    --with-optional-modules="test examples"

  * FlexibleSUSY's own dependency file generator is used instead of
    using the corresponding compiler capabilities.


Fixed bugs
==========

  * Bugfix (commit 20e88db): Use correct self-energy for 1st and 2nd
    generation charged leptons in *NoFV models.  Before commit 20e88db,
    the (heavy) tau self-energy was used to convert the running MS-bar
    electron and muon masses to DR-bar masses in *NoFV models.
    Corresponding test case:
    test_CMSSMNoFV_low_scale_constraint::test_delta_Yf()


Best regards,
Alex
