NMSSMCALC: A Program Package for the Calculation of Loop-Corrected Higgs Boson Masses and Decay Widths in the (Complex) NMSSM

J. Baglio, R. Grober, M. Muhlleitner +5

We present the program package NMSSMCALC for the calculation of the loop-corrected NMSSM Higgs boson masses and decay widths in the CP-conserving and CP-violating NMSSM. The full o…

NNLL Momentum-Space Resummation for Stop-Pair Production at the LHC

Alessandro Broggio, Andrea Ferroglia, Matthias Neubert +2

If supersymmetry near the TeV scale is realized in Nature, the pair production of scalar top squarks is expected to be observable at the Large Hadron Collider. Recently, effective…

Future Electron-Positron Colliders and the 4-Dimensional Composite Higgs Model

Daniele Barducci, Stefania De Curtis, Stefano Moretti +1

In this note we analyse the prospects of a future electron-positron collider in testing a particular realisation of a composite Higgs model encompassing partial compositeness, name…

Higgs Boson in the 4DCHM: LHC phenomenology

D. Barducci, A. Belyaev, M. S. Brown +3

Composite Higgs models provide an elegant solution to the hierarchy problem present in the Standard Model (SM) and give an alternative pattern leading to the mechanism of Electro-W…

MSSM Higgs Self-Couplings: Two-Loop O(alpha_t alpha_s) Corrections

Mathias Brucherseifer, Ryan Gavin, Michael Spira

We analyze the minimal supersymmetric Higgs self-couplings at O(alpha_t alpha_s) within the effective potential approach. The two-loop corrections turn out to be of moderate size i…

LHC physics of extra gauge bosons in the 4D Composite Higgs Model

D. Barducci, A. Belyaev, S. De Curtis +2

We study the phenomenology of both the Neutral Current (NC) and Charged Current (CC) Drell-Yan (DY) processes at the Large Hadron Collider (LHC) within a 4 Dimensional realization…

Matching Squark Pair Production at NLO with Parton Showers

Ryan Gavin, Christian Hangst, Michael Krämer +4

The pair production of squarks is one of the main search channels for supersymmetry at the LHC. We present a fully differential calculation of the next-to-leading order (NLO) SUSY-…

Approximate NNLO Predictions for the Stop-Pair Production Cross Section at the LHC

Alessandro Broggio, Andrea Ferroglia, Matthias Neubert +2

If the minimal supersymmetric standard model at scales of around 1 TeV is realized in nature, the total top-squark pair production cross section should be measurable at the CERN La…

Finite-width effects in unstable-particle production at hadron colliders

P. Falgari, A. S. Papanastasiou, A. Signer

We present a general formalism for the calculation of finite-width contributions to the differential production cross sections of unstable particles at hadron colliders. In this fo…

Effective Lagrangian for a light Higgs-like scalar

Roberto Contino, Margherita Ghezzi, Christophe Grojean +2

We reconsider the effective Lagrangian that describes a light Higgs-like boson and better clarify a few issues which were not exhaustively addressed in the previous literature. In…

The Higgs Singlet extension parameter space in the light of the LHC discovery

Giovanni Marco Pruna, Tania Robens

In this note we propose an overview on the current theoretical and experimental limits on a Higgs singlet extension of the Standard Model. We assume that the Boson which has recent…

The 4-Dimensional Composite Higgs Model (4DCHM) and the 125 GeV Higgs-like signals at the LHC

D. Barducci, A. Belyaev, M. S. Brown +3

We show that the 4-Dimensional Composite Higgs Model (4DCHM) could provide an even better explanation than the Standard Model (SM) of the current Large Hadron Collider (LHC) data p…
