Subject: [Flexiblesusy-announce] FlexibleSUSY version 1.2.3
Message-ID: <5623ABC5.4030600@desy.de>
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
