A bstract We develop the idea that unprecedented precision in Standard Model (SM) measurements, with further improvement at HL-LHC, enables new searches for physics Beyond (BSM). As an illustration, we demonstrate measured kinematic distributions of ℓ + "Image missing" final state not only determine mass W boson, but are also sensitive to light physics. Such a search thus requires simultaneous fit BSM and SM parameters, “unifying” measurements LHC Tevatron. In this paper, complete program...
This work had two goals, to study the effect of hand dominance on myoelectric signal variables and fatigue indexes in back muscles assess repeatability estimates such variables. Myoelectric manifestations muscle were studied right left longissimus dorsi five right-handed left-handed normal male subjects. signals (M waves), evoked by stimulation applied a muscle's motor point, detected with surface electrodes. Each test consisted eliciting tetanic contraction 30 s duration supramaximal at 25...
The reproducibility of surface myoelectric signal measurements is paramount importance for clinical applications electromyography (EMG) techniques. repeatability electrically-evoked shape (M-wave) as well spectral and amplitude parameters, conduction velocity elicited torque was tested, in isometric conditions, on the tibialis anterior muscle 10 normal subjects. Contractions were by stimulation main motor point repeated after removal replacement detection electrodes same carefully marked...
We show that the mW measurement is a direct probe of New Physics (NP) contributing to ℓ+MET, independently from indirect tests via electroweak fit. Such NP modifies kinematic distributions used extract mW, necessitating simultaneous fit and NP. This effect can in principle bias measurement, but only limited extent for our considered models. Given that, we demonstrate agreement at high-precision with SM-predicted shapes results bounds competitive to, if not exceeding, existing ones two...
We analyze signals at the Large Hadron Collider (LHC) from production and decay of Kaluza-Klein (KK) gravitons in context "extended" warped extra-dimensional models, where standard model (SM) Higgs fermion fields are restricted to be in-between usual ultraviolet/Planck brane a $\sim O(10)$ TeV (new, "intermediate") brane, whereas SM gauge (and gravity) propagate further down O( \hbox{TeV} )$ infrared brane. Such framework suppresses flavor violation stemming KK particle effects, while...
This report summarizes the work of Energy Frontier Topical Group on EW Physics: Heavy flavor and top quark physics (EF03) 2021 Community Summer Study (Snowmass). It aims to highlight potential top-quark studies heavy-flavor production processes (bottom charm) at HL-LHC possible future hadron lepton colliders running scenarios.
Abstract The Muon g -2 Experiment at Fermilab uses a gaseous straw tracking detector to make detailed measurements of the stored muon beam profile, which are essential for experiment achieve its uncertainty goals. Positrons from decays spiral inward and pass through before striking an electromagnetic calorimeter. is therefore located inside vacuum chamber in region where magnetic field large non-uniform. As such, must have low leak rate maintain high-quality vacuum, be non-magnetic so as not...
We develop the idea that unprecedented precision in Standard Model (SM) measurements, with further improvement at HL-LHC, enables new searches for physics Beyond (BSM).As an illustration, we demonstrate measured kinematic distributions of lepton$+MET$ final state not only determine mass $W$ boson, but are also sensitive to light physics. Such a search thus requires simultaneous fit BSM and SM parameters, "unifying" measurements LHC Tevatron. In this paper, complete program initiated our...
Electrically evoked myoelectric signals (MES) may be expected to provide information about muscle properties more objectively than voluntary MES (1); To test the sensitivity of electrically small physiological differences some parameters where studied on right and left longissimus dorsi (RLD LLD) five handed (RH) (LH) healthy young subjects. Measurements were repeated times in different days for a total 100 contractions. Supramaximal electrical stimulation was applied with monopolar...
While the warped extra-dimensional models provide an attractive solution to both gauge and flavor hierarchy problems, mass scale of new particles predicted by minimal would be beyond reach LHC. Models extended extra dimensions have been proposed evade these issues their collider implications investigated for last decade. This white paper summarizes recent developments in context phenomenology. The strategies lessons are broad, a template extend experimental program, cover wider class signals...
We first review the decade-old, broad collider physics research program dubbed energy-peaks. consider energy distribution of a massless particle in lab frame arising from two-body decay heavy produced unpolarized, whose boost is arbitrary. Remarkably, location peak this child particle's identical to its single-valued rest parent, which function parent's mass and that other product. summarize generalizations types variety applications BSM. The energy-peak idea can also furnish measurement top...
A bstract We develop a method for the determination of top quark mass using distribution decay length B -hadrons originating from its decay. This technique is based on our earlier observation regarding location peak b energy distribution. Such “energy-peak” methods enjoy greater degree model-independence with respect to kinematics production compared proposals. The CMS experiment has implemented energy-peak associated -jet as an approximation energy. new uses -hadron lengths, which are...
We show that the $m_W$ measurement is a direct probe of New Physics (NP) contributing to lepton and missing transverse momentum ($\ell+MET$), independently from indirect tests via electroweak fit. Such NP modifies kinematic distributions used extract $m_W$, necessitating simultaneous fit NP. This effect can in principle bias measurement, but only limited extent for our considered models. Given that, we demonstrate agreement at high-precision with SM-predicted shapes results bounds...
