Year end update

Since the last post, we have been joined by Barilang Mawlong as a Research Associate. She is an expert on B-physics and brings in much needed expertise in this field to our group.

Some of the projects mentioned in the earlier posts have been completed.

The WW paper on the Littlest Higgs Model has been completed and published in the JHEP. It can be found here.

A letter has been written on the scalar K pi form factor and just posted on the arxiv.

Ongoing activities

Gauhar Abbas, B. Ananthanarayan, I. Sentitemsu Imsong and S. Ramanan are engaged in extending previous works to include phase of timelike region and modulus for the pi-pi electromagnetic formfactor as well as the pi K scalar and form factors and also include spacelike constraints whenever possible.

B. Ananthanarayan and Monalisa Patra are studying W-pair production at the ILC and possibilities of obtaining bounds on
(a) parameters of the littlest Higgs model in collaboration with P. Poulose and (b) on anomalous gauge boson couplings in collaboration with Saurabh D. Rindani

Welcome to Barilang Mawlong

Dr. Barilang Mawlong who has just finished her Ph. D. from the University of Hyderabad and is an expert on B physics will now join the group. This message is to welcome her.

Publications update

Several publications have emerged from the group. The analysis of the inclusion of spacelike constraints and phase of timelike data with the observable Pi'(-Q^2) has resulted in a publication authored by Gauhar Abbas, B. Ananthanarayan and S. Ramanan. Soon afterwards the study of the pi K scalar form factor was taken up, and the inclusion of constraints from the well-known Callan-Treiman point, and now from the soft Kaon analog of the point, now christened the second Callan-Treiman point was taken up. It has been shown that based on such analyticity techniques one can now estimate the correction at the second point to the one-loop result which amounts to about 3%. The resulting publication by Gauhar Abbas and B. Ananthanarayan reports these findings.

Monalisa Patra and a summer student Rituparna Chakrabarti along with B. Ananthanarayan analyzed the present status of the single top events at Fermilab and reported it for the Research News section of Current Science, which can be found here.

Strongfrontier Orientation Programme

An orientation programme for the Strong Frontier workshop will take place at our seminar hall on Wednesday, 10th December 2008 at 10 am. The idea is to provide a brief background on what the topics are that will be covered at the workshop.


Update: Report prepared by Gauhar

Anant gave an orientation talk for Strong Frontier 2009 workshop. He explained various things,e.g. chiral symmetry breaking, chiral perturbation theory,string theory and nonpertubative methods in QCD etc. He spoke of the importance of these issues in testing QCD as an appropriate theory of strong interactions. He also dicussed Heavy Quark Symmetry and Heavy Quark Effective Theory which have quite importance in Heavy flavour Physics.

Links to recent talks given by members of the group

Here are links to some recent talks by members of the group.

Gauhar's talk given on November 5, 2008 on the work of Kobayashi and Maskawa is here.

Anant's talk given on November 11, 2008 on dispersive and analyticity constraints on the pion formfactor is here.

Anant's talk given on September 10, 2008 at the time of the first beam at LHC is here.

Joint publications of group members as on Nov. 20, 2008

We will also provide links to joint publications of group members.

Anant and Sunethra have two joint publications, on analyticity and analyticity and dispersive contstraints on the pion form factor. At the time of this post, the first is published while the second is a preprint. These may be found here and here.

Gauhar and Anant have a joint publication with Kriti Ashok and S. Uma Sankar in Current Sciene as a Research News publication on the anomaly in the charged and neutral direct CP violation signals in the B meson system. The link is here.
