“…When we refer to the stability of (4) at some energy Q (with the use of the couplings at that scale), we are assuming that the field values are at the scale Q. Note that the field values are the only functional arguments when talking about a potential like (4), and therefore the appropriate renormalization scale must also be at that scale. For λ 3 > 0, the third condition in (7) could potentially be violated only for field values φ around m h2 , regardless of the renormalization scale Q [26].…”

“…where Q * is some energy scale where the extra positivity condition is violated; see Appendix C. 4 Therefore, Q ± ∼ m h2 when the extra positivity condition is saturated, that is λ 1 λ 2 = λ 3 /4. From (60) it follows that Q ± ∼ m h2 when all the λ i are roughly at the same scale.…”

“…The behavior of the running couplings depends sensitively on the weak scale boundary conditions, among which the mass of the Higgs boson is perhaps the most critical. The measured Higgs mass m H = 125.5 ± 0.5 GeV [3][4][5][6] corresponds to a Higgs quartic coupling λ close to zero when renormalized at energies above Λ ∼ 10 11 GeV.…”

Majorana dark matter through the Higgs portal under the vacuum stability lamppost

et al. 2015

We study the vacuum stability of a minimal Higgs portal model in which the standard model (SM) particle spectrum is extended to include one complex scalar field and one Dirac fermion. These new fields are singlets under the SM gauge group and are charged under a global U (1) symmetry. Breaking of this U (1) symmetry results in a massless Goldstone boson, a massive CPeven scalar, and splits the Dirac fermion into two new mass-eigenstates, corresponding to Majorana fermions. The lightest Majorana fermion (w) is absolutely stable, providing a plausible dark matter (DM) candidate. We show that interactions between the Higgs sector and the lightest Majorana fermion which are strong enough to yield a thermal relic abundance consistent with observation can easily destabilize the electroweak vacuum or drive the theory into a non-perturbative regime at an energy scale well below the Planck mass. However, we also demonstrate that there is a region of the parameter space which develops a stable vacuum (up to the Planck scale), satisfies the relic abundance, and is in agreement with direct DM searches. Such an interesting region of the parameter space corresponds to DM masses 350 GeV mw 1 TeV. The region of interest is within reach of second generation DM direct detection experiments.

“…The data reveal indeed that jets are strongly attenuated as they traverse a quark-gluon plasma, and a careful study of this attenuation can help pinning down various properties of the plasma, such as some of its transport coefficients. Particularly interesting for the present work is the detailed analysis of the missing energy observed in inbalanced dijet events [1,2,3,4]. The reconstruction of the energy and angular distribution of jets particles around the dijet axis has been achieved, and evidence has been obtained that the missing energy in the away side jet is found in the form of soft particles radiated at very large angles from the direction of the jet.…”

Angular distribution of medium-induced QCD cascades

2015

We provide a complete description of the angular distribution of gluons in a medium-induced QCD cascade. We identify two components in the distribution, a soft component dominated by soft multiple scatterings, and a hard component dominated by a few hard scatterings. The typical angle that marks the boundary between these two components is determined analytically as a function of the energy of the observed gluon and the size of the medium. We construct the complete solution (beyond the diffusion approximation) in the regime where multiple branchings dominate the dynamics of the cascade in the form of a power series in the number of collisions with the medium particles. The coefficients of this expansions are related to the moments of the distribution in the diffusion approximation and are determined analytically. The angular distribution may be useful in phenomenological studies of jet shapes in heavy-ion collisions.

“…The factorisation breaking is usually explained as a consequence of additional partonic interactions between both hadrons which destroy the diffractive event signature -the rapidity gap [5]. Similar effect was recently observed at LHC by the CMS collaboration [6].…”

The cross section of the diffractive process ep → eX p is presented where the system X contains at least two jets and the leading final state proton is tagged in the H1 Very Forward Proton Spectrometer (VFPS). The measurement is performed for photoproduction with Q 2 < 2 GeV 2 in photon virtuality and for deep-inelastic-scattering with 4 GeV 2 < Q 2 < 80 GeV 2 . Measured cross sections are compared to next-to-leading order QCD calculations based on diffractive parton distribution functions extracted from measurements of inclusive cross sections in diffractive deep-inelasticscattering. The results are discussed with focus on the validity of the factorisation theorem for these processes.
