Feedback: Baby Boomer Manager Offends Millennial Trainee
Hana Tan, a recently employed college graduate was in the midst of her training program when her manager\u27s manager, a fellow named Eric, humiliated her, in her view, in front of her training group by criticizing her use of a ponytail. She wondered, Should I quit? Do I have to take this stuff to get ahead? Should I report him? We discuss the incident in the context of phenomenology, Snyder\u27s self monitoring, Goffman\u27s presentation of self, embeddedness and the role of frank feedback
Improved bounds on W-W' mixing with ATLAS resonant WZ production data at the LHC at TeV
New charged vector bosons decaying into gauge boson pairs are
predicted in many scenarios of new physics, including models with an extended
gauge sector (EGM). Due to the large variety of models (other unification
groups, models with Supersymmetry, Little Higgs Models, Extra Dimensions) the
more general EGM approach is here considered. For what concerns
-production, these models are parametrised by two parameters, the
mass and the - mixing parameter .
The diboson production allows to place stringent constraints on this
mixing angle and the mass, which we determine and present for the first
time by using data from collisions at TeV recorded by the
ATLAS detector at the CERN LHC, with integrated luminosity of 36.1 fb.
By comparing the experimental limits to the theoretical predictions for the
total cross section of resonant production and its subsequent decay into
pairs, we show that the derived constraints on the mixing angle for the
benchmark model are rather small, between and , i.e.,
greatly improved with respect to those derived from the global analysis of
electroweak data which yield . We combine the limits derived
from production data with those obtained from the process in
order to significantly extend the exclusion region in the -
parameter plane and obtain the most stringent exclusion limits to date. We
present the combined allowed parameter space for the EGM boson after
incorporating indirect constraints from low energy electroweak data, direct
search constraints from Tevatron and from the LHC Run I with 7 and 8 TeV as
well as at Run II with 13 TeV data.Comment: 13 pages, 5 figures. arXiv admin note: text overlap with

Legitimizing radical new medical services
Physicians enjoy considerable liberty in the creation of entrepreneurial ventures in the new frontiers of medicine. Professional societies may opine about a new procedure but professionals may feel free to ignore their counsel as well. Two case studies are used to discuss this method of new venture creation; the cases are trait selection through pre-implantation genetic diagnosis and female cosmetic genital surgery (FCGS), both controversial practices. We discuss the ethics and legitimacy of both and how one can use theory to analyze whether or not these are legitimate businesses and how to develop them
Contact interactions and polarized beams at a Linear Collider
We discuss contact-interaction searches in the processes e^+e^-\to
\mu^+\mu^-, b\bar{b} and c\bar{c} at an e^+e^- Linear Collider with c.m. energy
\sqrt{s}=0.5 TeV and with longitudinally polarized beams. The measurement of
polarized cross sections allows to study the individual helicity cross
sections, and consequently to derive separate, model-independent, constraints
on the four-fermion contact interaction couplings. We evaluate the reach on
those parameters foreseeable in the case of both electron and positron
polarization fixed at some reference values, and compare it with the situation
where only electron polarization is available. The analysis is based on
polarized integrated cross sections with optimal kinematical cuts that can
improve the sensitivity to the relevant couplings. While electron polarization
would by itself allow such an analysis, the additional positron polarization
(with no loss of beam intensity) and optimization can have a crucial role in
improving the sensitivity to the new interactions.Comment: 13 pages, LaTeX, including figure
Signals of Warped Extra Dimensions at the LHC
We discuss the signatures of the spin-2 graviton excitations predicted by the
Randall-Sundrum model with one warped extra dimension, in dilepton and diphoton
production at LHC. By using a specific angular analysis, we assess the ranges
in mass and coupling constant where such gravitons can be discriminated against
competitor spin-1 and spin-0 objects, that potentially could manifest
themselves in these processes with the same mass and rate of events. Depending
on the value of the coupling constant to quarks and leptons, the numerical
results indicate graviton identification mass ranges up to 1.1-2.4 TeV and
1.6-3.2 TeV for LHC nominal energy of 14 TeV and time-integrated luminosity of
10 and 100~, respectively.Comment: 8 pages, Talk given at QCD@Work - International Workshop on QCD -

Center-Edge Asymmetry at Hadron Colliders
We investigate the possibility of using the center-edge asymmetry to
distinguish graviton exchange from other new physics effects at hadron
colliders. Specifically, we study lepton-pair production within the ADD and RS
scenarios. At the Tevatron, the graviton-Z interference is the most important
contribution to the center-edge asymmetry, whereas at the LHC, the dominant
contribution comes from gluon fusion via graviton exchange, which has no
analogue at e^+ e^- colliders. We find that spin-2 and spin-1 exchange can be
distinguished up to an ADD cut-off scale, M_H, of about 5 TeV, at the 95% CL.
In the RS scenario, spin-2 resonances can be identified in most of the favored
parameter space.Comment: 23 pages, including figure
