Searching for Heavier Higgs Boson via Di-Higgs Production at LHC Run-2
The LHC discovery of a light Higgs particle (125GeV) opens up new
prospect for searching heavier Higgs boson(s) at the LHC Run-2, which will
unambiguously point to new physics beyond the standard model (SM). We study the
detection of a heavier neutral Higgs boson via di-Higgs production
channel at the LHC (14TeV), . This
directly probes the cubic Higgs interaction, which exists in most
extensions of the SM Higgs sector. For the decay products of final states
, we include both pure leptonic mode and semi-leptonic mode .
We analyze signals and backgrounds by performing fast detector simulation for
the full processes and , over the mass range
GeV. For generic two-Higgs-doublet models (2HDM), we present the
discovery reach of the heavier Higgs boson at the LHC Run-2, and compare it
with the current Higgs global fit of the 2HDM parameter space.Comment: Phys.Lett.B Final Version. 16pp (9 Figs + 4 Tables). Only minor

N′-(2-Hydroxy-3-methoxybenzylidene)-1,3-benzodioxole-5-carbohydrazide monohydrate
Single crystals of the title compound, C16H14N2O5·H2O, were obtained from a condensation reaction of 1,3-benzodioxole-5-carbohydrazide and 3-methoxysalicylaldehyde in a 95% ethanol solution. The asymmetric unit consists of a Schiff base molecule, which assumes an E configuration with respect to the C=N bond, and a water molecule of crystallization. The dihedral angle between the two substituted benzene rings is 12.7 (2)°. In the crystal structure, molecules are linked through intermolecular N—H⋯O and O—H⋯O hydrogen bonds, forming layers parallel to the bc plane
Why Do Women Have Longer Unemployment Durations than Men in Post-Restructuring Urban China?
This paper provides the first systematic analysis of the reasons why women endure longer unemployment durations than men in post-restructuring urban China using data obtained from a national representative household survey. Rejecting the view that women are less earnest than men in their desire for employment, the analysis shows that women's job search efforts are handicapped by lack of access to social networks, social stereotyping (that married women are unreliable employees), unequal access to social reemployment services stemming from sex segregation prior to the displacement, and wage discrimination in the post-restructuring labor market.Gender inequality, unemployment duration, Oaxaca-decomposition
Further study of the global minimum constraint on the two-Higgs-doublet models: LHC searches for heavy Higgs bosons
The usually considered vacuum of the two-Higgs-doublet model (2HDM) could be
unstable if it locates at a local but not global minimum (GM) of the scalar
potential. By requiring the vacuum to be a GM, we obtain an additional
constraint, namely the GM constraint, on the scalar potential. In this work, we
explore the GM constraint on the -conserving general 2HDM. This constraint
is found to put limits on the soft breaking mass parameter
and also squeeze the heavy -even Higgs boson mass into larger
values for the case. Combined with the current global signal fits
from the LHC measurements of the 125 GeV Higgs boson, we discuss the
phenomenological implications for the heavy Higgs boson searches at the LHC.Comment: 19 pages, 9 figures, 2 tables; v2: Refs added, one-loop level results
